I want to give a shout out to Jordan who called me this morning. We had a lengthy discussion about his crankshaft failure, his findings so far. I think we're starting to a clearer picture as to why crankshafts are popping in the early trucks.
However, it seems, due to his efforts the NHTSA has opened an investigation into this failure mode.
The case ID is PE23030. Here is a link to the pdf:
edit: Somehow I put up the wrong pdf... not even sure how I the wrong one!
If that pdf is to be believed, it suggests there was just shy of 40,000 of these engines manufactured.
Jordan was hoping to get some elevated visibility on this subject and perhaps get more people to complain to the NHTSA. I strongly support his initiative. He also will be doing a full tear down of the engine and hopefully will have the time and resources to investigate the failure without bias.
It would also seem that the crankshaft failing is secondary to the real problem, which appears to be oil delivery. I'm just repeating his research, so I hope he joins the forum and chimes in for himself.
I would also like to point out, that if you were deleted and turned up it may not be helpful to this investigation as it would give Cummins and Nissan something to point their fingers at and wash their hands of this issue. If the problem can be conclusively laid on oil delivery, then being turned up shouldn't matter anymore.
