16’ 6.4 285k and lost a lifter. Had dealership PUP 0w-40 it’s whole life except like 2 changes I needed to do myself because of work. I haven’t found a reputable shop I felt comfortable doing the work. I can get a create engine from Mopar for 6k, plus 3k dealer install. Comes with warranty if I get the dealership to install. My question is would you replace lifters and cam or go with the crate motor? I just bought a new 1500 as my daily driver so this truck will be for towing heavy, hunting, general real truck stuff. My 1500 will be mainly a pavement princess. If you think cam/lifters heads redone, please recommend a shop. I don’t mind traveling for quality work on a truck I will have for the next 5+ years.
