P7100 Fuel In The Crankcase???

Any clue where to start? got about 3" extra of oil level on the stick. Smells like diesel.

A stuck (not firing) Injector will cause that.

Pump could be leaking internally, as could the lift pump. Does the truck have a miss to it? How's the fuel pressure?

Idles smooth, fuel pressure was 20psi at idle. my lift pump was leaking from the weep hole so i removed it and used my frame mounted electric pump 15psi. Not sure if the fuel may have leaked into engine before i removed the lift pump, didn't check it till today.
THANKS: TOMMY

Drain the oil, and monitor accordingly. I'd suspect you'd have a good miss with a bad injector, and possibly with the IP leaking as well.

Well: drained the oil, refilled to the bottom mark, drove it 6 miles now it's on the top mark. Guess it's time to look for a good pump shop.
