i have a 2006 2500 cummins and yesterday i was on my way home from town and my engine light was on i ran it and it said low oil pressure when i got out of the truck i realized my whole truck is covered in oil i checked my oil and it has diesel in it i would say about a gallon when i start it white smoke pours out is this an injector problem?

 

Sounds like injector problem to me.

 

Me too, sounds like you have at least one injector stuck open....

 

ive had a few do this. they just get too full and blow all the oil and fuel right through the blow by tube. both the times it happened to me i had cracked injectors and they leaked out
