A good friend of mine owns a diesel truck performance/ mechanic shop. He steered me far away from them. He told me that a whole bunch of the 6.7's are waiting at the dealer for a new motor after the CRANK breaks. He said it has been happening at around the 100k mark so it is not covered of coarse. My boss man has one with 65k on it with no problems to date been getting about 15 mpg. Good luck

i talked with ole steven the other day if thats who your referring to and i'll tell you what man he sure does know his stuff when it comes to any diesel i'll give him that im probably about to have him rebuild my tranny for my 12 valve
