Need some help, My check guage light went on, check my guages and saw that there was not oil pressure. Pulled over and checked dip stick. Oil level was about 2 inches above fill line. Ilde is also ruff and I can smell diesel. Also I noticed some smoke comming out of the breather tube under the truck. Any suggestions.

Thanks.

 

Fuel in the crankcase sounds like a bad injector. Better not drive it till you know for sure. Washing of the oil will kill a piston and engine bearings.

 

What he said, don't drive it as it doesn't take long to destroy the engine with fuel in the oil.
