need some insight
 

working on a 2005 model. cranks fine cold, heavy white smoke at idle..zero knock. Rev it a little and you get a pretty heavy knock. Pulled the head...found number 6 to be "wet" versus the other 5. Any ideas? thanks for any help in advance!

Pulled the head for nothing but hey great experience! Replace your injectors! #6 is bad do them all! Call Todd at T&C diesel! Google him tell him Andy CA sent you!

Thanks for the info
 

Yea, it wasn't that bad pulling the head. I usually service duramax's and PSD's. Took this venture to learn a little about the cummins. Thank you so much for the info

Ok...replaced all 6 injectors...knock is still there. Killed injectors 1 by 1 with my solis ultra and still have the knock!!!

Hmm Knock with no power is hard I'd start with the valve train check your rockers! Worst case you lost a connecting rod bearing! Caused by a bad injector!
