my 06 cummins has diesel in the oil, blows lots of white smoke at idle and blew oil all over my truck right before that my engine light came on and said low oil pressure what could this be? is it injector problems?

 

If you got diesel in the oil, then it sounds like the seal around you pistons seems to be leaking. Your rings might be fried or one of your injectors burnt a hole in you piston, cause by putting a stream of fuel on one part of the piston instead of spraying fuel. This is the worse case scenario, I don't have much Cummins experience, but this might be a place to start.

 

Well if you got fuel in the oil, and white smoke, and blew bunch of oil down the side of your truck, it almost sounds like rings or a melted piston. Blowing oil all over your truck which I'm assuming came from the blow by by relieving pressure which is usually caused by rings when you have an excessive amount of blow by.

 

You lost an injector! To start then lost a piston possibly! Pull the injectors and take a look with a bore scope! Or just pull the head! If you washed the internals with diesel probably will need a total rebuild!

 

Dang let us know what comes of it!

 

will do it will be a couple of days really busy at work

 

Sent you a PM with some options for testing injectors.
