They are. It only has 160K miles, but I think neglected/improper maintenance caused the damage to cylinder 6, having coolant going into the cylinder never is good. We've found a lot of dumb little things when fixing up the truck. The other 5 cylinders look fresh out of the factory. I'm sure we could do the rings plus the hone and it'll be fine for another 160K. It ran fine before besides needing lifters, and those were probably bad from it sitting for a few years when the owner was too old to drive it anymore.
