I just wanted to give some of you a heads up on my findings. my truck started smoking like crazy and had small mis, so i talked to my enjine man and he said turbo or piston. I asked if a failed head gasket could make clouds of blue smoke and he said no! the compresion will push the oil the other way and i agreed. So i pulled turbo and it was full of oil in the exaust in so i eliminated. So i figured bad piston. I decided to pull head before pulling whole motor and ther it was a huge hole in head gasket between #2 cylinder and oil passage. Im glad i did not pull whole motor like my engine man told me. Maybee this will help one of you with finding problem. now i just have to do head gasket and check timing.
