once the PMD, OPS and cooling issues are addressed the 6.5 is a great engine.
read other 6,5 post and you will see how common pmd problem is, but there is good easy fix, same of the OPS, and on the cooling if the 6.5 is run hot (and most gages read low) the heads crack between the valves, to prevent that i advise the 6.5 water mist injection, it will also help with POWER and MPG.

i have 2001 chevy silverado that has had repeated problems with the fuel injectors. Is this a reoccurring problem? It has been back at the dealership so many times now I have lost track and I have spent a great deal of money, i wonder if its time to just trade it in. I am also checking out ford diesels and wonder if they are subject to the same type of reoccuring problem

I have a 1998 6.5 turbo in a gmc 1 ton pickup.After owning the truck for only 3 months,there was blue smoke from the exaust.The mech.at the dealer said it was some kind of a fuel problem but had no clue what it could be.After about 5 months and only 85,000 miles,the oil level started raiseing,and the water level was droping.It doesnt take much of a rocket scientist to know that isnt right.When the motor was taken apart,it was discovered that the block was cracked in the webing in between where the crank bolts up and the cylinders.Of course nobody wants to take responsibility.has anybody ever seen this before,and can anyone tell me what caused it.THANKS

1998 6.5 3500 automatic- just bought it with 123k. Idles fine and powers up fine but seems to cut out while pressing the trottle just slightlty. Replaced the pedal relay(gm garage said too) but still no go. Runs up to 60mph but seems to come off power when you let up a little on the throttle. It runs through the gears at full throttle but down shifts out of OD when you let up on pedal. Seems to have way too much throttle for such a slight pedal depression. GM garage said tranny is fine. Help...

I have a 1993 6.5 turbo. Bought it new over 12 years ago. Have used it for heavy duty work ie- pull a Kubota L35 loader backhoe. This truck has never failed to start ( Until this past weekend and after 12 years a lift pump was installed. Hell I just had the first fuel filter changed this past week STG. If you can find a 1993 6.5 with low miles buy it as they are the only ones built with the mechanical style fuel pump system. A far superior and trouble free system. 12 years and only oil changes Beat that Toyota, this truck is used for Work not pleasure!

jeff,
Sounds like you have classic PMD failure symptoms;
The PDC Remote kit is the best and only lasting way to fix the PMD failure problem,
it is a remote mounting system complete with new PMD, cooler and a remote harness that allows mounting away from the hot engine, (no cutting, no splicing, it just PLUGS-IN, this is very as NOT to alter the vehicle wiring which would often result in problems on the 6.5)
The PDC Remote kit is very easy to install, and no special tools, no adjustments, no settings and no trip to the dealer, the PDC simply plugs in and you mount it on the firewall.
The PDC (Pump Driver Cooler) is ONLY available from www.duramax.bizhosting.com
PMD failure often results in a stalling condition that can be sudden and very dangerous, and I do not let my loved ones ride in any GM efi 6.5 Diesel vehicle that does not have the PDC Remote kit installed.

the PMD is the culprit in about 98% or more of 6.5 diesels stalling problems, you already know you need to get the PDC, yet then say your only answer is the dealer, so FYI your posts reads like that of the the TROLL.

And could that be it? I've been to dealers .I give up on them.It has always run perfect other than the toggle switch throttle.

I ordered my 1998 Chevy K2500 new from the factory and just turned 108,000 miles. Religious about changing oil every 2500 miles. The dealer just installed the third fuel injection pump in October. November I started loosing coolant. Early December I noticed it pumping blue smoke. Two dealers later I discovered it was over full of oil. Changed the oil in the morning and thirty miles later had a gallon extra in the crank. Dealer is washing their hands because it's 8000 miles and a year and a half out of warranty. I'm looking at long block (because I don't know if it's head or block). What the heck is going on. I see others with the same problem. Help!!! Dealer wants ten grand to fix it.

I have a 1997 6.5 that has performed great. Never even the stalling problems that I see so often on your site. My problem was an oil leak an the oil cooler line where it had chaffed the metal section at a bracket. The dealership ordered and replaced both oil cooler lines for me on Dec 28th. On Dec 29th, I took off on a trip and after about 300 miles, the upper oil cooler line blew apart at the engine where the line has a 90 degree elbow into a swivel connection into a 1-1/4" nut going to the back of the engine. This happened on the interstate and blew seven quarts of oil out in 30 seconds before I could stop. I got under the truck and pushed the oil line back into the hole. It re-seated and, of course, would not pull back out when the dealer checked it. The truck made it about 60 more miles before it threw a bearing. The dealer is insistant there is no way this line could have blown apart. I was there. Ever heard of this problem before? Any suggestions on additonal info? Thanks.
