Message: Ill be driving along 70 or so and the check engine light comes on, the motor bucks a time or two and then the engine goes dead or has no power. I put it neutral and turn the key off and back on and most of the time its back in business. This is a recurring proplem with the truck. Thanks for any help.

Auston 1/07/2003 16:49:06	RE: Chevy 6.5 Turbo ? Message: Actually, mine ended up being the Injector pump as most of these type problems are. To be more specific, the Electronics mounted on the side of the injector pump. My injectors were worn out too. Soon there after I replaced boths heads (cracked up bad enough to loose compression (engine missing on one cylinder) and therefore filling the crankcase with diesel. And shortly after that I lost the trans. In other words, I should have parked it at 269,000 miles. Im now at 290,000 and things are going well. I thought it was a pain to install the pump. Now I know its a pain to replace the heads :). Hope that helps.

IF YOU ALREADY HAVE THE NEW STYLE INJECTION PUMP. YOU JUST WANT TO CHECK YOUR PMD (PUMP MOUNTED DRIVER) THE BLACK BOX ON THE DRIVERS SIDE OF THE PUMP. i ALSO HEAR THAT YOU CAN FIND DRIVERS THAT MOUNT ON THE FENDERWELL. I HAVE FOUND DRIVERS THEY GO FOR ABOUT 300.00 IF YOU FIND ONE CHEAPER PLEASE E-MAIL ME I NEED ONE.

Auston 5/03/2003 02:43:42	RE: Chevy 6.5 Turbo ? Message: Another thing that can cause it to quit running is the Oil Pressure Switch located behind the fuel filter. If switch bad or oil pressure low fuel feed pump can shut down causing the truck to quit running. A bad fuel feed pump is sometimes the culprit.
Todd 5/05/2003 17:13:08	RE: Chevy 6.5 Turbo ? Message: Just bought a 94 suburban with a 6.5 Turbo diesel to replace my 1991 with a 6.2 diesel. On the way back to Mpls from LA the thing developed a knocking noise at idle that is heard inside the truck. Drove 2000 miles and used no oil. The injector tubes when listened to with a wooden stick seem to be making alot of noise at the same interval as the noise. The injecters towards the fire wall seem to be abit louder. Does any body know if the injectors make a lot of noise when they reach the end of there life. Mechanic at the local Chevy dealer says there is something that causing the noise to reverberate into the truck he called it a non electrical grounding problem kind of like what would happen if an exhaust pipe touched the frame. Any ideas?
Auston 5/05/2003 18:22:08	RE: Chevy 6.5 Turbo ? Message: A real knock is usually caused by mechanical looseness. One that is most noticable at idle speed might be in the engine. If what your noticing is a miss check your dip stick and make sure your engine isnt putting diesel in the crankcase oil. This can happen when compression is lost in one or more cylinders. Good luck.
Todd 5/05/2003 23:40:03	RE: Chevy 6.5 Turbo ? Message: Don't you think if the engine was engine was putting fuel into the oil there would be some sign of an increasing oil level within the pan or dip stick reading after driving the truck 2000 miles? When I mentioned the truck did'nt use any oil I guess I wasn't completly telling the truth the oil level was going down ever so slightly. A freind of mine seems to think its a slight exhaust leak at the turbo? Can the turbo leak from within the exhaust side of the turbo into the intake side?
Auston 5/06/2003 22:14:48	RE: Chevy 6.5 Turbo ? Message: I would think that the turbo could leak from the exhaust side because thats were the pressure is. When my truck lost compression in one cylinder the oil level was 1/2 quart over full after 200 miles or so. I dont see how the turbo leaking could make the knocking noise. A bad connecting rod bearing could make a heck of a noise though. You could try draining your used motor oil through a filter of some kind to see if you have any metal particles there. Good luck with it.
todd 5/07/2003 08:05:03	RE: Chevy 6.5 Turbo ? Message: It's fixed!!! The source of the knock was the aluminum coolant tube that runs front to back between the valve cover and the intake. This tube has a aluminum bracket welded to itself that is attached or bolted to the intake manifold. The bracket was loose and rattling between the bolts and the manifold, thus transferring the knocking sound into the heater housing inside the truck.
chad 5/07/2003 18:40:52	RE: Chevy 6.5 Turbo ? Message: i have a 95 6.5 turbo aswell and it seems some times to stall or go into high idle. Also making alot more noise. the service engine soon light will stay on as well. I can shut it off and wait awhile and then the truck will run fine.
Auston 5/07/2003 19:59:24	RE: Chevy 6.5 Turbo ? Message: Sounds like the PMD. When mine would stall I could drop it in neutral and recrank it. After doing this trick a while it eventually craped out completely leaving me stranded and having to pay for a wrecker. FYI: I now have 296K miles on mine with original motor. I have replaced the Trans (2), Injector pump/pmd (2) and both heads.

artie 5/22/2003 17:24:57	RE: Chevy 6.5 Turbo ? Message: have a 1995 Silverado with a 6.5 turbo. After driving a while and accelerating- the check eng lite illuminates (related to turbo pressure?) and it seems to act like a gas job with a bad plug! Push on the accelerator and stumbling quits. Light goes out when pressure released on the pedal. I just bought the truck an it ran along good for about 20 miles then acted like it was running low on fuel, 136.000. Changed fuel filter & air filter etc. Too bad no boost pr. guage. Vac is 15" at waste gate.
6.5 chad 5/22/2003 18:42:23	RE: Chevy 6.5 Turbo ? Message: have you checked to see what codes you have. It sounds like your waste gate selinoid. That will be code 78. I had the same problam and the code said waste gate selinoid.
kenneth 5/23/2003 00:14:28	RE: Chevy 6.5 Turbo ? Message: motor has miss 1&6 seem to have low or no compression also used to get fuel in oil but replaced intake gasket and seemed to fix that problem is that possible? idles real rough levels out fair when racing up engine but still has a miss.
Auston 5/23/2003 00:33:27	RE: Chevy 6.5 Turbo ? Message: No. Intake gasket has nothing to do with fuel in oil, but a blown head gasket could. These engines are terrible about cracking the heads too. You cannot get by with no or low compression with these engines for very long. A no combustion situation simply allows the fuel to work its way around the piston rings and down to the crankcase. Good luck.
kenneth 5/23/2003 15:27:08	RE: Chevy 6.5 Turbo ? Message: if compression on 1&6 is week how can i tell if its the rings or in the heads?
Auston 5/23/2003 16:19:02	RE: Chevy 6.5 Turbo ? Message: I would think it more likely to be head or gasket related since it involves 2 cylinders. I lost #6 myself and suspect its because the heat can't escape that area. There is just too much stuff right there with the exhaust manifold, turbo, starter, sheilds, etc. Both of my heads were busted up though. Cracks were through the seats on both heads. You might try holding your hand over the oil filler hole while the engine is running to check for ring blowby. I've done this on tractors and it might work a 6.5.

Joshua Allen 6/24/2003 19:24:50	RE: Chevy 6.5 Turbo ? Message: I have a 94 3500 6.5L turbo diesel that seems to be having similar problems. The truck has been sitting with only an occasional crank for the last three years, so I expected some problems. Now she's a bitch to crank, and when it finally does, smoke bellows out the wastegate end of the turbo. So far I've been told it could be water in the oil or a bad fuel pump, but I'm thinking its directly turbo related. These Borg Warners run off their own oil line, right? Could oil in the turbo be causing the smoke? Or is it simply leaking from the exhaust itself?
Auston 6/24/2003 19:52:06	RE: Chevy 6.5 Turbo ? Message: The turbo has nothing to do with hard cranking. IF the smoke is white thats just all the fuel your pumping into the cylinder heads spinning the motor. If black then certainly thats probably oil related and your turbos seals could be shot. This problem your having starting the truck could be related to the PMD previously mentioned on this board. Its possible to connect a new PMD without physically installing it to see if this corrects the problem. Its takes patience and some skill but you can disconnect your present PMDs elec. connection and connect to a new PMD laying close by and they try cranking. Im thinking youll see a difference. OF course Im assuming you've already replaced fuel & air filters, and you have good clean fuel and charged batteries. FYI: I keep a spare fuel pump and spare PMD with me at all times in my high mileage truck.

Mike 6/25/2003 14:41:03	RE: Chevy 6.5 Turbo ? Message: Have a 93 turbo diesel and it is pushing oil through the PVC cannister and down into the turbo charger. The PVC was stuck and I replaced it ($57) but there's still oil getting by. The engine seems to have a lot of pressure blowing out the top where the PVC goes in. I'm using about a quart every 1000 miles. Any thoughts on that? Could that pressure be turbo related?
Oscar Berlanga 6/27/2003 16:36:10	RE: Chevy 6.5 Turbo ? Message: In a similar situation with my '94 chevy 3500, the 6.5 needed a new injection pump (problem started at 116,000 miles, got diagnosed by chevy dealer, quoted $2100. Problem was intermittent at the time so I blew it off. At 126,000 miles, it quit totally. Towed and new rebuilt pump in Fife, WA cost $1780. Was told that Chev was offering free fix if before 120K miles. Took up with chevy showing the previous diagnostic from dealership. Got nothing. Too bad !

Auston 7/11/2003 18:55:03	RE: Chevy 6.5 Turbo ? Message: I like these trucks, but you do have to work on them. I dont think you can buy one and drive it 500K miles without a few injector pumps, maybe a pair of heads, a pair of transmissions, vacuum pump or two, you get the idea. IE: I just put a second oil pressure switch on mine in the last 20K miles. When all is right these trucks run great and have plenty of power for pulling. Im hoping the engine block will last 500k without building because that and the rearend is all I have left thats original in my drivetrain.

Joshua Allen 7/13/2003 18:03:24	Assessing PMD Problems Message: After running through many theoritical situations with my 6.5L, it seems that the PMD would be the most likely problem from the information I see here. The smoke coming from the turbo at startup is more of a white gray color, so it has to be something fuel related. I've tried putting fresh diesel in it, replacing all the filters, and checking the oil for water. But before I go off spending $300 for a new PMD, is there anyway I can check it directly for failure? Should it be running a certain voltage or something that I can check with a multimeter, etc? Where is it located in the engine bay exactly?
Auston 7/13/2003 19:13:43	RE: Chevy 6.5 Turbo ? Message: The first thing I would do is to make sure to Fuel Delivery pump or Lift Pump as its sometimes called is working properly. A little know fact is that these engines can run (sometimes kinda bad) with this pump not even working. Its located just below the drivers door on the inside of the frame. With engine running reach down and hold this pump and you should feel it vibrating some since its a reciprocating pump. Its really an elec. coil moving back and forth and that pumps the fuel. #1 cause for this pump not working is the oil pressure switch located behind the fuel filter. It seems to have a start mode and a run mode. It will not work properly if switch is defective or no oil pressure. OK now to answer your question. The PMD is mounted on the side of the Fuel Injector Pump. With the engine cover off look at the engine from the drivers side and nestled down under and in front of the intake manifold is the pump. Maybe you could borrow a PMD or buy one from somebody off Ebay for about 1/2 of list. Now with some long needlenoise pliers, plug it in without removing the manifold or the old PMD and see what you have. Good Luck!

I pull a 35' horse trailer and on long hills it gets hot enough for the check gauge light to come on, and doesn't have much power at all. What can I add to increase power? Has anyone tried the Stinger kit from Banks? Would an intercooler help? Any advice would be appreciated.
Auston 7/19/2003 22:23:54	RE: Chevy 6.5 Turbo ? Message: On a 93' 6.5 diesel I would check the Wastegate first and foremost. If your vacuum pump is half wornout therefore not providing enough vacuum to properly actuate the wastegate then theres your power problem right there. Of course pulling a loaded 35' horse trailer up long steep hills is asking alot of any pickup.

The last pump is the new model/design/manufacture and has not given me any trouble for the last 25K miles, 107K present. The problem I have is power, in '94 I was towing a 8500# (loaded) trailer, I did this for four (4) years about five (5) times a year, distance ranged from 300 to 1400 miles (round trip), with speeds ranging from 65 to 80 MPH. I didn't tow anything from '98 to '02. This year I purchased a new trailer which weighs approx. 4500# (loaded), I cannot go over 63 MPH or I will be close to red lining and this is with a lighter trailer. No power, Can anybody help.

Steve 8/09/2003 08:48:37	RE: Chevy 6.5 Turbo ? Message: I have a '94 Chev (3500) w/6.5 diesel which has a stall problem. Periodically when I start it it will run for a few seconds and then abruptly stall. I recrank it for maybe a minute and it starts again. It has never quit while in motion but only right after initial starting. It is unpredictable when it might happen and will always(so far) restart within a minutes cranking. I have been told to replace the PMD PDC and the oil pressure switch, but thats a lot of work and dough. Will the codes show the fault, and has anyone else had a similar problem? Also, can anyone direct me to the optical sensor which sends signal or power to the lift pump?
Auston 8/09/2003 16:02:22	RE: Chevy 6.5 Turbo ? Message: It sounds like the lift pump is not switching to run mode properly and that is usually due to a bad oil pressure switch which you can probably buy for less than $30.00. The switch is located just behind the fuel filter housing. Take a 17mm ratchet and remove the fuel filter housing bolts and then shift stuff around so that you can get to the oil pressure switch on the right side. They make a special socket for it but I use a 6pt. 1/2 drive deep well socket. I think its 1 1/16.

Bert 8/09/2003 22:06:03	RE: Chevy 6.5 Turbo ? Message: My 93' 6.5 was stalling when idiling or after just starting. After cranking for 30 seconds or so it would always restart. After removing the fuel pump and testing it, it was not working at all, but the engine would still run. When I opened the pitcock to check for water in the fuel it broke the vacuum that was allowing the engine to suck fuel without a fuel pump (I guess). Wouldn't start again until the pump was replaced. I wouldn't have believed it, but it is so. New fuel pump was $98 at Pepboys. Runs great now and stopped stalling.
Auston 8/09/2003 22:14:52	RE: Chevy 6.5 Turbo ? Message: One note about it all. Ive had 3 pressure switches and 2 lift pumps go bad on my truck. Not one optical sensor has given me a problem. When you first turn the ignition switch to on position you should hear that solenoid "click". Good luck.

After Auston had suggested my problem was either the turbo unit or the wastgate I checked it out. I pulled the air cleaner plastic off at the turbocharger and found the impeller fins full of oil, and there was a little puddle at the bottom. Another thing I noticed is for the past year I haven't heard that turbo whine, I used to hear, when I would step off the accelerator. This is my second question, can anybody make a suggestion based on experience on a company to purchased a remanufactured turbo unit from to replace the present one. I have been on the web looking but any suggestions would be great appreciated. I also purchased a boost gauge that I will install with the new turbo unit so in the future I will not wonder where my pulling power went. Thanks, Rick

vince 8/14/2003 16:26:46	RE: Chevy 6.5 Turbo ? Message: Steve, Auston HELP!! PLEASE Just bought this truck 96 chev dually 6.5 l diesel, turbo, last week and bought it knowing it needed work, it would not even hardly idle when I bought it, drove it home 70 miles and it ran a ton better, idled pretty good also. Question is this dude has a TON of blow bye and it has not been doing it long you can tell by the the oil build up around it. The smoke when you stand on it is dark which doesn't bother me but when just cruising down the road it has alot of white light blue smoke, found a cracked vacuum line going to the pull off valve for the turbo, I assume this is called the wastegate vavle??, fixed that and seemed a little better, today I took the stock exhaust off and and put on a 3" strait exhaust( NO Restrictions at all ;), seems to run a ton worse now, didn't change the smoking at all, but took effort to get to 70 mph, as where before it had probably more power than any 6.5 I had ever drove.also I do beleive the heads have been replaced from looking at them and I know the intake gasket has been replaced also. #1 My questions are what is up with all the blow bye? is it just wore out? (152,000 miles) #2 Does a 6.5 diesel need back pressure in the exhaust? #3 I know how to rebuild gasoline engines is a diesel that much differn't? #4 Should a chev diesel turbo "whine" as much as say a powerstroke or cummins? mine does not. Thanks so much for the help I have already received and the help I will get in the future!! I just pulled the intake tube off the turbo and it is full of oil! I assume that it could be coming from all the blow bye, but don't know for sure. What is the best way to clean it out and can I run the turbo safely without the tube from the pvc cannister hooked up to it? can a bad pvc cannister be causing the blow bye?
Auston 8/14/2003 16:54:24	RE: Chevy 6.5 Turbo ? Message: The smoke is probably fuel sometimes, oil sometimes, and both at times. Its possible to crank with intake off and watch for fuel forced through cracks of a knocked out valve seat. In your case, I dont know if it will tell you anthing. It does sound like youve lost compression with all the smoke and lack of power as well as rough idle. Check compression with a proper diesel compression gauge on all cylinders. That will probably tell you alot, then you can get to work. Exhaust sizing is the least of your problems right now. The turbos seals may be leaking the oil you see there and in the intake. No, you cant hear the turbo on that engine as much as the others. Good luck with it.

Auston 8/18/2003 20:54:29	RE: Chevy 6.5 Turbo ? Message: So thats twice that same motor has done that, right? Im surprised it still runs to be honest about it. Didnt you say previously that its running rough with alot of blowby. If your loading the engine up with alot of unburnt fuel who knows whats happening. That fuel may be kicking off and making the engine go crazy. The way I understand it the Injector pump (specifically the pmd)has a logical governor built in that will reduce fuel to the cylinders thereby reducing rpms when redline is detected. Thats whats suppose to happen, but PMD cannot control fuel already delivered! Call a good authorized Stanadyne Pump Shop and ask them about it. If you keep driving it Im thinkin your gonna blow the works. Driving it that way could be dangerous. As for a conversion: Everything about it is different. Gas & Diesel engines are controlled differently by their respective computers so the wiring harness and the all the trimmings are different. Heck, even the fuel tanks are different. Gas has intank pump, diesel does not. I suspect that last one could be overcome though. Hope that all helps. Check compression!

Im just a shadetree mechanic that looked to this board for help (Feb 2002) and have tried to give back to it when I think I can contribute. Compression check on one of these is done with a high pressure compression tester made specifically for diesel engine testing. I know Snap On has it and Im sure the others do too. On the 6.5 the compression can be checked through the glowplug threaded hole. Only one certain adapter works for it. Some of these are quite hard to get to and under the turbo special extra long adapters (can be homemade even) may be needed to accomplish this.

Dave R 8/19/2003 09:34:51	RE: Chevy 6.5 Turbo ? Message: I've got the same problems that many have previously mentioned and I think I've done all of the checks that were recommended. Can anyone tell me if I'm missing somehting? Here's my story- I have a '95 Chevy 6.5L Turbo Diesel, Auto, 119K. I recently replaced the pump mounted driver to take care of the stalling. The problem I have now is that the Service Engine Soon light still turns on and off frequently, even after clearing the codes. It also seems that the turbo won't kick in every once in a while. The codes given are 32, 33, 36 and 78. After clearing, the same codes return after a little driving. Dealer tells me they are just history codes and that I shouldn't worry about it. As long as the light comes on, I'm going to worry. I've checked the vacuum pump (23mmHg @ idle), wastegate holds vacuum, EGR holds vacuum, all vacuum lines hold vacuum. All solenoids (turbo, EGR vlv, EGR vent) appear to be working as they start clicking/vibrating when I unplug and replug. There is ~17mmHg vacuum at wastegate at idle. Vacuum at EGR fluctuates from 0 to 18 mmHg every couple seconds (at idle). The lift pump is working. There is a little white smoke at start-up or when I floor it. There is a little puddle of oil in the turbo intake in front of the impeller fins. Otherwise everything else seems to be OK. I notice the light frequently comes on when cruising at a constant speed and will shut off when I let off the pedal (or turn cruise control off). It will also sometimes turn on when idling in gear. Will turn off if I put it in park or drive away. Any idea why the light doesn't just stay on? Are the problems that set the codes intermittent? Any help would truly be appreciated. Thank You
Auston 8/19/2003 09:50:13	RE: Chevy 6.5 Turbo ? Message: I would suggest one thing you might be missing is the fact that the problem with the 78 code (wastegate Solenoid) is not a constant problem but rather its intermittent. My electrical connector was bad, but only showed up at highway speeds. The Check Engine Light would come on and if I let off the accelerator the light usually went out.

Still stalls? 2) Get a PMD and connect it to the pump while still in the truck and see if that fixes it. 3)if that doesnt work Id find the pump shop that builds those pumps in your area and get a quote on a pump from them. It takes a scan tool (set up to do it) to set the timing properly. As for new or reman. I dont know if they are still building em new. It may be that only reman is out there, but you do want one with the latest updates. Hope that helps.

You'll be going down the road the check engine light comes on and the engine goes into backup fuel(no power, no turbo, code 18 and 35)Turn the key off and restart it runs fine. But sometimes it will totally die going down the road. It gets a check engine light and codes 18 and 19. PMD??? I already changed the oil pressure switch and fixed all the fuel leaks. Did notice that the battery cable from the right battery to the left one was corroded bad. Cleaned it up and it took care of the long crank time starting problem. But it still stalls out whenever it feels like it. Also, I noticed that when I plugged the trailer lights into it it died out. No codes. I think this was a result of the brake control being hooked to the left battery, which had a bad cable. Would the truck stall out if one of the batteries was bad?? One other thing I noticed is that the ignition switch doesn't always come back all the way into the run position after starting it. Could this cause the lift pump to not work thus causing it to stall while going down the road and popping up these codes???

Wes 8/28/2003 16:15:08	RE: Chevy 6.5 Turbo ? Message: Yes it is mounted on the side of the injection pump. Think it is getting to hot?? It seems to do it more when it is warm out or when pulling a long hard grade.
Auston 8/28/2003 16:53:24	RE: Chevy 6.5 Turbo ? Message: When my PMD first started going bad the engine would go dead right after starting it in real hot weather. Then a month or so later it would go dead at highway speeds. I could always get it to recrank. Then one day it just died and left me stranded. Interesting thing about the PMD is that it gets very hot itself. Being attached to the pump is designed to help cool if off.
Wes 8/28/2003 17:44:47	RE: Chevy 6.5 Turbo ? Message: I guess I'll be ordering the remote mount setup. Where is the best place to mount this? Where is the resistor, that is supposed to be swapped to the new PMD, located? Where is the best place to get the remote mount setup? Do the #'s have to match, from old to new, when changing the PMD?? The PMD that is in this truck is #34264. The extra PMD's I have are numbered 30214. Can they be interchanged?? How about the injector pumps can they be interchanged? I was just given two injector pumps, complete, from the Chev. dealer. They were warranteed ones that were supposed to be destroyed. The truck I'm working on is a 1994 2500 with the vin code F. One of the pumps is supposed to be out of a 1997 the other one I don't know what year.
Auston 8/28/2003 18:25:03	RE: Chevy 6.5 Turbo ? Message: I dont know about remote mounting but the resistor is in the connector part of the PMD. they make a special tool to swap it. #5 is the most common Im told. As for swapping PMDs, Ive swapped 3 in my truck and didnt pay attention to #s or resistors and they've worked fine. There are two different pumps installed on the 94 so compare the numbers. Higher fuel rate was delivered by some 94 pumps. If you need one, yet get the other, the truck will not run good. There are several #s on the pump itself and your not looking at the one you need to. If I remember right one of the pumps is a 5288. I found this, might be interesting to some. Shows how the resistors work. http://www.thedieselpage.com/reviews/FSDCooler.htm
Wes 8/28/2003 23:19:09	RE: Chevy 6.5 Turbo ? Message: Have you found that just replacing the PMD has taken care of the problem most of the time?? Even if you only put it back onto the pump instead of remote mounting it?? This guy only wants to keep it another year and then he's buying a new truck. Is the remote mount setup worth the money??? I believe it is only another couple hundred bucks to get it.
paul 8/28/2003 23:28:03	RE: Chevy 6.5 Turbo ? Message: The truck I have had the PMD mounted to the firewall. Cant say how long it lasted, but , they spliced wires and left old PMD on pump. It died shortly after I bought it.I would think that without a heat sink that this was not the best move. I know it had to be a lot less work than putting it back on the inj. pump.

Wes 9/02/2003 23:06:30	RE: Chevy 6.5 Turbo ? Message: Your vehicle has faulted back to the back up fuel system. When it does this it loses the turbo boost and thus the low power problem. It's also called the limp mode. Many things can cause this. First check the wiring where the wires for the PCM goes into the fire wall. The wires may be rubbing on the AC metal line. Also check your lift pump inside the frame below the drivers door. Make sure it is working. If not it could be your oil pressure switch that's bad. All in all it is probably your PMD on the fuel injection pump that is bad. If it is I would take this to a Chev. Dealer and get it checked out. The injection pump is warranteed for 120,000 miles/11 years. I believe that the only thing that you have to pay for is the fuel system being cleaned (lines and fuel tank) but they may also warrantee this too. Definitely take it in if you check the earlier items and find nothing wrong.

phil 9/16/2003 07:29:28	RE: Chevy 6.5 Turbo ? Message: albert are you sure you want to put that much boost to her? the 6.5 is a 21.3:1 static compression motor. if you run 20psi boost pressure, youre probably going to blow a head gasket or worse. i think there is a reason GM set the wastegate at 7psi. more compression means more efficiency and they would want all the effeciency they could get im sure, but if you run too much boost, you shorten the life of the motor. unless you have changed to 18:1 pistons, i wouldnt recommend that much boost, you should also think of how much extra heat that turbo will be creating in the intake. (just a new exhaust ended up frying my PMD, already on the way out, but the exhuast accelerated that). anyway, just a word of caution, let me know how that turbo works for you and what kind of longevity you get from the motor.

Message: I have found that the some (most) 1994-2001 GMC and Chevy C/K,G or P model trucks & 97-98 school bus with the 6.5 diesel has an extened warranty on the electric fuel injection pump. The warranty is for 120000 miles or 11 years. General Motors put this letter out on May 2003(bulletin # 00064D). There is a list of other parts under this warranty also (Driver Kit F/Pmp Mdl, intake manifold gasket and more). It states that if you have had the pump replaced by a Chevy or GMC they will reimburse you for your out of pocket moneys. The work has to be perfomed by a GM dealer. Chevy customer service # 800-222-1020 GMC # 800-462-8782. Most of the problems I have read about these engines lead to the injector pump (engine light, bad fuel milage and smokes at start ect.) All points toward the pump? I am tamking my to the dealership next week to have to pump replaced. I will know then if that is my problem. Good luck

Message: I just bought a 1998 GMC Sierra 6.5L turbo and have had my share of problems.Black smoke under a load, slight hesitation while under a load.All these problems happen after the truck is up to temperature ( 185 deg) I changed the fuel filter, map sensor, turbo boost sensor, waste gate solenoid and just for grins had the batteries checked out. I also measured the vacuum at the waste gate while idleing ( 15" Hg ) The vacuum source seems good ( 27"Hg). I also physically checked the operation on the waste gate.It was fine. Waste gate acuator holds vacuum as does the egr valve. I needed to see what the vacuum was doing while driving, so I hooked a vacuum guage to the egr line and hung on the hood were I could see it. At first all was well, egr vacuum cutting in and out as the truck in and out of load conditions. Then the truck started its black smoke thing under a load at that point i noticed the vacuum to the egr never dropped out. The egr valve had a constant supply of vacuum.This I thought caused the turbo to loose boost because of the hole the egr valve left open. . I pulled over, popped the hood and pulled the vacuum line off the egr valve. It snapped shut.I rapped all the solenoids ( egr vacuum, egr vent ) I even pulled the vacuum line off the map sensor ( firewall) the vacuum supply returned. I was convinced the map sensor was bad and replaced it. All was well until today. Same story as above with a twist. When the truck started loosing power I pulled over, popped the hood and disconnected then re-connected the map sensor ( firewall) I could here the egr slam shut and the truck ran great for the rest of my trip home today.Just to be complete, I measured the voltage at the map sensor +5 vdc and a seemingly ground .05 VDC. I think the ECM is having trouble getting the proper signal from the map sensor.I I also checked to see if the ECM harness by the firewall was frayed. It looks fine. Tonight I pulled the glove box out and re-seated the ECM. I think it might have a ground issue. Sorry to be so long winded. I hope some of this helps. I would welcome any overlooked items left un-checked.. Thanks

I have the same problem as most with the code 78 and on and off ses light. I have changed the waste gate solenoid and no good. Thought I found an open wire, added a new segment no good. Can I check for voltage at the waste gate solenoid? Also, does anyone know of a cheap air filter kit? Would the Grand National turbo air filter kits work? Has anyone tried the fixed waste gate lever from turbo masters? Thanks, J
Jo 10/03/2003 21:56:18	RE: Chevy 6.5 Turbo ? Message: Bought a 1994 K3500 6.5L TD, manual trans (L-1-2-3-OD) with 149k on it, in June, knew the truck had some problems when we got it, but it was cheap enough. It has a well, we call it a herky jerky problem. Going down the road if we let off its very abubt, kind of like it hit something. If we are going down a hill with the truck on cruise control it will jerk until we either speed up or just let off entirely. We cannot maintain one constant speed with it if there is any downward incline. Today we were out on a back road and put the truck in neutral to let it coast down a hill and it died. Started right back up and then revved up and died again. Started right back up and seemed fine after that accept for the usual jerking. We recently replaced the vacuum pump, fuel filter, oil pressure sending unit, dual mass flywheel, and clutch (were replaced with a solid flywheel and upgraded clutch kit from Luk). It has an upgraded injection pump and the only codes its showing are Injector pulse width short, injector pulse width long (those are in the history) and the only current one is a code pertaining to the throttle position, which the mechanic said was some sort of short in the accelerator pedal. There is a problem with the pedal, on occation when going or just starting out it won't work, have to let off and hit it again to get the truck to go, but not sure if this is related to the other problem. Any ideas? We are at a loss and so is everyone else when it comes to this truck. Other than this one problem the truck runs awesome, has great power, gets wonderful fuel economy and is just a really nice truck. Its currently at the diesel mechanic to see if the short in the accelerator pedal is the problem. We are on diesel mechanic number 2, the first one got tired of fighting with the truck.

Even though the truck isn't running perfect.....its got a fuel system problem that we have yet to figure out. It still gets a consistant 18.3 mpg mixed driving and 15 mpg towing, on one trip of highway only it managed 20 mpg (we don't take it on long trips much, can't trust it). Our 96 K2500 6.5L TD auto trans that we used to have....royal pain in the rear.....got a consistant 16.9 mpg no matter what we did with it. I would be really disappointed with 12 to 13 mpg, I guess I could see it in a dually, but a SRW, that seems low. Now if we could just figure out the herky jerky with our truck we'd be doing good. At least our truck is the appropriate color.....green, color of all the money it sucks up.
Ed Morgan 10/07/2003 13:35:42	RE: Chevy 6.5 Turbo ? Message: The '98 K3500 dually 6.5TD that I have has 4:10 gears, but I put on bigger tires, 235-85s. They are almost 10% taller then the 225-75s that it had, so that dropped the gear ratio by almost 10%. The truck runs in the 6.5s power curve of 1700 to 2200 RPMs at 50 to 65 MPH, this is what I wanted beacuse if you run it there you get the best mileage. It should get better fuel mileage after the engine is broken in. I took the truck up to the Keweenaw Peninsula in Upper Michigan this last weekend, I had a 1968 Avion 12ft pickup camper on the truck with a full load of stuff and I guess the whole load was at least 10,000 LBS. The top of the U.P. is pretty rugged with switch backs,7% grades and some long uphills. The 6.5 handeled it fine, I never wished that I still had my old 454GH (gas hog) back. After reading all the bad stuff about the GM 6.5TD, it make you think that GM built a bad engine, because you never hear anything about people being satisfied with the engine. So far I guess that I do like it, but by reading about the problems, I will know what to look for when I have a problem.
phil 10/07/2003 14:05:26	RE: Chevy 6.5 Turbo ? Message: I love my 6.5 in my tahoe, dont get me wrong, just always looking for improvement. has anyone ever played with intercoolers on the 6.5? im tossing around the idea right now. i think it would help the motor alot. the stock settings kick the wastegate in at 7psi which i can understand, but i think that the motor would be fine with 7psi at cooler temperatures. i dont have a guage, but i imagine the intake temperature in the truck has to be around 150 deg F when it is warmed up and higher than that when the turbo is spooled. if i can drop the intake temp to even to 100 degrees, that will spell alot more fresh air for the motor. im interested to hear any reply from anyone who has done anything similar or who has an reasons against doing so. hope to hear some replies

Dimitrios 10/14/2003 21:24:10	RE: Chevy 6.5 Turbo ? Message: I have a 1994 Chevrolet 6.5 Liter Turbo Diesel... About 16 months ago my truck would just die for no reason, I had to wait about 10 minutes to get it to start. And it seemed to just get worse. So finally I took it to the dealer, they said it was the fuel injection system, they charged $2400 and the problem continued, not as bad, but continued. We took it back to the dealer and complained and they said that while it was constantly dieing, and constantly being started it ruined the batteries, so we got two new batteries. Ever since then it has ran beautiful, no problems, until now. All of a sudden one night, I was listening to music, and I had the truck started sitting there, and it died. The first thing I thought was, OH NO! NOT AGAIN! :( , well it started back up fine. I went riding around and it died, and I was going around a turn and the power steering went out, it was scary. But anyhow, it just kept getting worse and worse. So I took it to the dealer again, and they said they couldn't find anything wrong with it. They charged about $300 dollars to run tests and told me nothing is wrong, I was mad and got in started it hit the gas real hard, and it died. They still said they can't find nothing wrong. The dealer where the truck was bought cant fix their own product, I didn't know what to do. So now I found this site, and hope someone has some suggestions for me. The dealer said my fuel injection is good, everything is good. But it dies. They said it could be that the computer is bad, or it could be the lift pump, or it could be this, or that. They said the only way to find out is to put a new one, and if thats not the problem, I will have to keep it. If someone can please give me some kind of information on how or what to do in this situation, I would greatly appreciate it. Thanks in advance.

Auston 10/15/2003 17:24:49	RE: Chevy 6.5 Turbo ? Message: Hey, The PMD can have a problem and never give a trouble code. Ive read they fail most often without ever giving a code. A new part does not always mean a good part. One thing you could do is verify that fuel is properly delivered to the injector pump. I would try this: Crank truck and unscrew vent cap at top of fuel filter. If fuel does not come rushing out, thats a problem and is affecting injector pump performance. Search for the problem in this order (1) dirty fuel filter, (2) Bad Oil pressure switch, (3) lift pump problem. Good luck.
Dimitrios 10/15/2003 20:15:19	RE: Chevy 6.5 Turbo ? Message: Auston, thanks for the tips. I just wanted to say I was outside working on it for about 4 and a half hours today, after I got out of school until now. I have recently changed the fuel filter, that was my first thought, that was not the problem. I just checked the lift pump by touching it while the truck was on and feeling that vibrating feeling in it, (like you said to do in a earlier post) and it seems fine, I even tried to unhook the lift pump and it didnt shut off. I also seen that the box on the left, im not sure what its called, was loose, its some kind of filter.. I took it off and the filter was so dirty. I dought this is my problem, but you never know. Is there a possibility that the lift pump may still be bad, and also, where can I locate the PMD, and how can I check it? Also, how can I check the Oil Pressure Switch? Any help you can give me, I will greatly appreciate it.. thanks in advance. :)

phil 10/16/2003 09:17:44	RE: Chevy 6.5 Turbo ? Message: Dimitrious The PMD is located on the side of the injection pump. This is located in the center top of the motor in the valley immediately above the intake manifold. it is hard to get to. there is a little black box on the side of the injection pump that should say stanadyne. this is the pmd. its an electronic component that both gives off heat and is very sensitive to it. I have remotely mounted mine on the inner fender on a piece of finned aluminum with a cooling fan on it. these parts are very heat sensitive as they are electronic components. i highly recommend remotely mounting them, I am even debating putting mine behind the firewall in the passenger compartment where it will see cooler temperatures. i dont believe there is any way to test a PMD short of buying a new one. they are not cheap either. I believe the best i could find was somewhere around 275$. good luck with it

David 10/16/2003 10:36:42	RE: Chevy 6.5 Turbo ? Message: Is moving the pmd recommended for all 6.5 turbos or just certain years?
phil 10/16/2003 11:43:59	RE: Chevy 6.5 Turbo ? Message: i got my pmd remote package at http://www.duramax.bizhosting.com/My_Truck/remote_pmd.htm. they did me fairly well with shippin, i paid to get the item immediately b/c i was immobilized basicly. all years have the same PMD mounting set up, and i think they probably all have the same problem with heat. the original design used the injection pump as a heat sink and planned on the "cooler" fuel to act as a coolant. the fuel would travel through the pump and cool the pump and the pmd. this backfired, especially when you live in warmer climates where your fuel temperature averages 80 degrees (black truck in florida). some aftermarket kits remotely mount the pmd on finned aluminum on the intake casting. this works, but if you have a free flowing exhaust, it will heat up the intake casting and with it the pmd. this is the set up i had until i put a gale banks exhaust with no cat on it. the new exhaust let the turbo work more and this heated up the intake and fryed the pmd i had in short order(it was already on the way out). that is why i remotely mounted on the innner fender, some people recommend on the fire wall. if i have another problem, mine is going behind the dash in the passenger compartment. I would recommend a remote PMD in all 6.5 diesels. the biggest problem these trucks have is heat and you want all your electronic components as far away from heat as possible.
Auston 10/16/2003 11:54:33	RE: Chevy 6.5 Turbo ? Message: Only problem with that idea is the amount of heat the PMD will put off. After running for 5 minutes a PMD is too hot to handle. I bet it will heat up your whole cab.

Auston 10/16/2003 13:10:59	RE: Chevy 6.5 Turbo ? Message: I have the PMD in the original place, but I keep a spare in the truck. I think the firewall mount with a proper heat sink as you have it is probably the best situation. A good friend of mine is a Stanadyne Certified Rebuilder and they told him the PMD sensed fuel/pump temp as part of the equation. Who knows? Its a weak link in the whole deal, thats for sure. If I suspect a problem with the PMD I just swap the connector to the backup PMD and have it laying on the intake for a temporary test. It gets hot as you know what on its on and real quick too.
Dimitrios 10/16/2003 14:22:34	RE: Chevy 6.5 Turbo ? Message: Is there anything cheaper than a PMD I can check if it has a problem. 300$ for something that may not work is alot of money. Especially since the dealership done got me for that much.
Auston 10/16/2003 14:59:02	RE: Chevy 6.5 Turbo ? Message: Try finding one to borrow. What was the warranty on the pump you recently bought? Buy one off Ebay. Is there a certified stanadyne pump shop in your area? They probably have take offs laying around and they are usually better than dealerships at finding out what wrong with these. Especially since its all Duramax now at the dealer. Remember when pump/pmd combos are replaced some of those PMDs are still good and hit the garbage anyway during the rebuild.
Dimitrios 10/17/2003 14:20:32	RE: Chevy 6.5 Turbo ? Message: Auston. I live in the middle of a small town, not really anything here. The closest dealership is 20 miles away, and they dont know what they are doing. The warranty on my pump was 12 months, and its 4 months over. So that is out of the question. If they replaced the fuel injection, they replaced the pmd, correct? You say the PMD was bad when the batteries had to be replaced? If so, it was just changed. Could this problem be from low batteries? I recently noticed that the power guage blinks down when air or blinker or anything electronic is on. The lights on the inside dim when I put on my air/heater. If im stopped the truck battery guage could be as low as 9 volts, and when going it goes back up to 12 but eventually gets down to 9. Sometimes when i put my blinker on and im going about 70 on a highway I notice the miles per hour jumps back 25-30 miles per hour and goes back. I asked the dealership if the batteries could cause this problem and they said the batteries are good. Can this be the problem?

I called the salesman who I bought it from and he told me the could do it cheaper, he lied it was the same price. I called a guy in Ohio for the injector pump and he told me that CHEVY has a warranty on that and it will be replaced for FREE. I called some chevy dealers and the agreed then I called CHEVY customer service and they told me that yes it will be done for FREE by any Chevy dealer. Just mention Special Policy # 00064D.

James 11/18/2003 22:13:23	RE: Chevy 6.5 Turbo ? Message: I have a 94 chev sub 4*4 3/4 ton 6.5 ~137k pump was replaced a few years back with a green tag pump.. About 2 weeks ago the truck stalled going up a gentle incline...towed it in to dealer...they start it up ok...no codes and check the fuel pressure after the lift pump and the fuel filter....pressure good...filter OK... so I pick up the truck and put in some diesel additive to take care of potential water in fuel...drives OK for one tank...with a few stumbles but no stalling....next tank starts stalling more even with the additive.... now the symptoms are stalling every few hundred yards...wait a minute...start and go a few more hundred yards.... drives better when warm.... Looked over the truck in detail...reseated computer in dash...connector to oil pressure unit behind the fuel filter etc..... checked the connector to the lift pump (drivers side frame rail) and find it full of diesel (from dealership pressure check?)...clean out /degrease connecter , start up the truck and back it out of garage... Let me know if this line of logic is plausible... - water problems in fuel stall the truck - dealer checks pressure and soaks lift pump electrical connector - lift pump becomes intermittant as diesel insulates (or shorts) across connector Thoughts Ideas Rebuttals ??
Auston 11/18/2003 22:47:18	RE: Chevy 6.5 Turbo ? Message: While truck is running open top of fuel filter container. If fuel shoots up an inch or two then fuel delivery pump is working properly. I would then suspect PMD on fuel pump next. Most times its injector pump electronics causing the stalls. If your using water remover type additives in the fuel that should take care of trace amounts of water. Always buy diesel from people who sell alot of it.
james 11/19/2003 11:35:02	RE: Chevy 6.5 Turbo ? Message: Cleaning the diesel from inside the electrical connector to the lift pump seems to have cured the truck.... started first time and idled for 45 minutes..just took it out to play in the snow drifts...lot's of power...no stumbles at all... On another front the tach doesn't go to rest position when I turn off the truck (stays at 600 rpm) when I turn the key on it goes to rest than functions normally when vehicle turned on .... sometimes when I rev the engine (in park) the speedo will jump....am I getting an intermittant short somewhere (and could this also be part of my stalling woes?)

Tim W. 11/23/2003 17:19:38	RE: Chevy 6.5 Turbo ? Message: I am looking for information on the dual tank system used on the C3500HD cab and chassis tucks wiht a 6.5turbo. I have a C1500 2wd, ext cab and would like to add an auxillary tank. The C3500 seems to have two lift pumps, one for each tank. There is no switch for the tanks like the 80's 6.2 litres had. The fuel gauge some how regiters for both tanks at once and the fuel seems to pump from both tanks at the same time as well. I believe this method is also used on the newer Duramax C4500 as well. I am also curious about something else. My C1500 automatic od tranny with the 6.5l turbo rivals the performance of any gas pickup for get up and go, yet a C3500HD with a flat deck empty drives like it is chained to a semi going the opposite direction. I was kind of leary about buying my c1500 at first for that reason, but it is fine. A similar c3500hd with a 5 speed manual tranny is better as far as power but the shift configuration makes you want to shift into reverse after you get to 5. The auto 3500 is a 2000 and the std is a 1998. Both good trucks for there intended uses.

Auston 11/29/2003 19:41:23	RE: Chevy 6.5 Turbo ? Message: If you dont notice a miss at idle then you have not lost compression in a cylinder. You may have a injector bad. The injectors atomize the fuel for proper combustion in the chamber. If one or more is not spraying fuel but is just squirting it then that could cause the problem you are experiencing. With a cracked head you might fill the crankcase with diesel fuel around the rings of the piston.

Auston 12/07/2003 19:41:53	RE: Chevy 6.5 Turbo ? Message: Did you check the oil level? It probably has too much in it because a quart or two is Diesel from a cracked head or blown head gasket. Sounds like engine is not firing on one or more cylinders. May be that the block is cracked (quite common). So you could buy that truck for a grand, buy a GM motor for $6K and a GM trans for $2K and you would have $9K invested in a 10 year old truck worth at the absolute tops $6K in very good condition. Is my math bad or could buying this one be a move in the wrong direction? FYI. A GM Tech II scan tool can tell you which cylinders are not firing if you can find one.

Batterys and radiator were destroyed in the wreck, but the keys were still in the ignition. They cleared the front of the engine and put batterys to it just to see what would happen. It fired right up like it was another day at the office. I just dont believe the other pickup truck engines are that good. Maybe if Cat ends up in one, just maybe.

Auston 12/11/2003 14:31:47	RE: Chevy 6.5 Turbo ? Message: I like and use a product called HiTack (spelling may be different). Its sold in a small can that has a brush in the lid. about all autoparts stores carry it I suspect. Its very tacky and helps keep the gasket in place for proper installation. Another way I've seen it done is to run a good bead inside the cover with high temp permatex where the gasket would rest and then installing as usual, not even using a gasket. I always use gaskets when possible and usually use the hi tack stuff to help make it stay put.

The v-8 diesel somehow has more inherent problems not matter who the manufacturer is. Even the 3208 Caterpillar was known for its problems.

One day thats gonna happen and it will not restart. I keep a good wrecker co. phone # handy for just that occurance. Some say you can pour water on the PMD and it will work again right away instead of waiting 5 minutes or so.. I havent tried that one but it might help you troubleshoot. Good luck with it.

ARTIE 12/23/2003 17:08:15	RE: Chevy 6.5 Turbo ? Message: After listening to the "experts" on the PMD and how it needs to be mounted I bought a new PMD and Cooler- NO DIFFERENCE- decided to check the temperature of the old one (now disconnected) and LO an BEHOLD it was COLD !!! Tells me one thing that is the Transistors that generates the heat and JUST maybe that affects the operation of the Injector Assy. As far as I am concerned I dumped good money down the drain. After considerable thought I have come to the conclusion that the Engineers at Stanadyne most assuredly had it worked out!
GmDieselTech 12/23/2003 21:02:44	RE: Chevy 6.5 Turbo ? Message: Artie, if the stanadyne engineers had it worked out, then why do the PMDs fail in record numbers? and why is it the most common part to fail on these engines? It sounds to me like you got the wrong 'cooler'. The PMD itself generates heat and why you need the proper cooler, heat transfer material and remote harness for OFF engine mounting, as the added heat from the engine kills the PMD, even worse when the lift pump is not working and the injection pump has to suck fuel, the added work = HEAT & WEAR. I've been at fixing these efi 6.5's since late 1993 when the 6.5 efi came out. I've tried every cooler made and then some... the PDC kit i mentioned earlier is the only LASTING fix. ---------- Happy Motoring-David GmDieselTech@Yahoo.com Administrator at Yahoo Autos Groups 'ChevyGmcDiesels" http://autos.groups.yahoo.com/group/chevygmcdiesels/

Mike 1/05/2004 04:03:08	RE: Chevy 6.5 Turbo ? Message: Blake, My 95' 2500 4X4 Suburban 6.5 TD had the same problem with "white smoke" in the exhaust. I pull a boat with my "BURB" (9K lbs on the hoof). I'm vigilant at watching gauges but alot can happen in seconds. While pulling one day I lost the coolant from a bad hose then the truck overheaded into the mid 200's within seconds. Shortly afterward the white smoke started. Slight at first and got worse over time. I then noticed that the white smoke seemed to smell like antifreeze. Long story short, I cracked the heads over five of the eight cylinders and as the cracks got worse so did the smoke as the coolant was leaking into the cylinders, heating into steam and leaving through the exhaust pipe. The steam sure did clean the exhaust! Fortunately there was no other mechanical/block damage and after a new set of heads ($1400), some grease under the nails and a hot air balloon full of cussing the truck runs great. Diesels need heat to run well HOWEVER, there is a limit on how much heat they will take and according to my source for heads the 6.5T seems to be more sensitive to heat than other heavier built blocks. The engine is suposed to be designed to shut down in an overheating event but don't rely on this! I learned the hard way to maintain a vigilant watch on gauges especially temp and oil. Happy Rattling!

The filter canister is not filling up with fuel, its like the fuel pump is not working. Checked fuel pump fuse, its good; Jumped fuel pump relay, nothing.

phil 1/05/2004 15:41:55	RE: Chevy 6.5 Turbo ? Message: your fuel pump is probably dead. try hot wiring the fuel pump to make sure it is getting voltage. if not replace it. the injection pump can draw fuel all the way from the tank, and when you finally broke the fuel system loose to change the filter, some air got in the lines and the injection pump can no longer draw fuel due to the air.
paul 1/05/2004 16:38:35	RE: Chevy 6.5 Turbo ? Message: Hi guys, I have a 1997 Silverado with a 6.5litre turbo. A few weeks ago, I had a small incident when I rear ended someone. Damage was minimal and the front bumper was pushed in slightly. Since that time, when RPM reaches 2300-2400, the engine seems to misfire and cruise control will kick out. Is there an explanation for this? Does it make sense that the incident would have anything to do with this? I have 74,000 KM on the engine and have no other previous problems.

IP: Logged Message: you will have to trace down that circuit to find the problem, the GM manuals are the best the set is about $130 form www.helminc.com GM's authorized distributor.]if you suspect teh fuel lift pump is blowing your fuse, simply unplug the lift pump and try again if not connected the fuse should not blow.
