I have oil in my fuel tank. Old long block replaced injector o rings did not fix. Got Used long block "good shape " my injectors With new O rings,turbo,high pressure oil pump & water pump is all i switched . Starts and runs < smooth> very littile smoke ;oil in fuel: for about 20 minutes oil pressure drops @ gauge dies . Check oil none on dip stick fill again about 2 gallons crank on it it finaily starts back;same as before: no leaks

It is either a cracked head or an oring, about all it can be. Can u see the oil in the tank? It sounds to me that the relief valve in the front cover is acting up and you are loosing oil to your high pressure oil pump.
