'94 6.5 diesel fuel in oil

[777stickman]

A friends '94 K2500 6.5 diesel. Oil level is rising from fuel (not coolant). There is no evidence of "hydraulicing" in the cylinders. It cranks fine and starts after 2-3 revolutions and runs fine. There is a fuel leak towards the rear of the motor while it's running that seems to have contaminated the clutch disk as it's slipping under load.

225,000 total miles. Motor replaced 110,00 miles ago with a complete '99 6.5. One fuel pump replacement since then.

Any and all suggestions and ideas are appreciated.

Could be a stuck injector allowing fuel to enter the engine. I'd find out what's going on before driving it any more. Very hard on bearings with contaminated oil.

Thanks for your reply. We've determined it's the injector pump seals. He is still trying to decide to fix or to junk as he's been thru this before many times with the pump.

Go HMS. 24, 48, 88 & 5!!!
