I have an 08 6.4 255k. Clean, no rust. Deleted etc. I’m new to this page as well as 1st time diesel owner. Just did the front end, had death wobble. I’m trying to figure out what will prolong the life span of the truck. I’ve heard the 6.4s are **** n expensive. What parts should I look into or keep an eye on. Had the no start issue but all electric was working, got a new PCM, kept getting locked out. Everything is running strong now. I use fuel additive “hot shots”/ hot shots for the oil as well. Overall work truck! Any feedback would be appreciated!
