[QUOTE="AshevilleEngine.com, post: 1347644, member: 11592"] There is a chance that cylinder had either excess fuel or coolant in it. If that happens, something has to give. That being said, we have found that a large percentage of connecting rods from 6.4 core engines are twisted. I think we figured out why but that's another story. If the connecting rod was twisted, the wrist pin is working at a strange angle and with everything fitting tighter in a newly machined block with new parts, what you described could possibly happen, although I've not personally heard of that happening. Unfortunately, with catastrophic damage to that cylinder, you can't rely on the condition of that connecting rod giving you good forensic evidence. [/QUOTE]
