Even if he bought the used engine, do you think he'd be able to install it by himself? If he can't just buy a shop manual, and do some simple deductive reasoning, I doubt he'll be able to jump to swapping engines. But hey, there's a chance he could do it.

Wow, I just peed myself reading all this silly crap. I like your idea that you snapped a ring because of a bolt that came loose from your engine side cover. WTF does that even mean??????????????????
