Well, the one I looked at today -seemed- nice enough. I was only really concerned about 2 things (and they may be major, dunno).

Big hesitation, bump-bump then go. Only happened once. Happened at full operating temp.

Clatter and tap from engine.

Walked away. Maybe it's no big deal, maybe it is. For what they wanted the truck needed to be perfect and it wasn't.

Change your oil hot and often.
