Archived Diesel fuel mixing with my engine oil

[JimHartshorn]

I have a 2001 Dodge Ram 2500 and I'm getting diesel fuel mixing in with my engine oil causing it to appear overfull when I check my oil. Is there a way that I can check the injectors and injector tubes? Or any other suggestions on how to pinpoint the problem?

have the injectors ever been pulled? How many miles on them? Pop the valve cover and see if you can spot fuel concentrated around one particular injector. Could be a leaking crossover tube or even a bad injector.

Yes, injectors were upgraded about 2 years ago, approximately 15K miles on them. Have removed cover and could not see any fuel leaking.

What brand injector? Did you install new crush washers and o rings? Does the truck run any different? Higher EGT's than normal?

Three places to look: injector body o-rings, VP44 front seal, stuck open injector. Do you have more than 20 PSI from the lift pump as this may blow the VP44 seal.

DDP ISBXX High Flow Injectors, yes washers and O rings were new. Doesn't seem to run any different but it is blowing more smoke and EGT's are higher than normal. I am unsure of the PSI from the lift pump, I have a FASS 150 on it.

Sounds like a bad injector. I would pull them and have them pop tested.

Thanks for the help

Your FASS 150 pressure should be fine.
