For those who haven't seen his channel before, it's probably best described as an engine autopsy channel. He runs a yard, and basically dismantles bad engines and points out what went wrong, probably why, and all kinds of things like that. He's funny, it's generally family friendly-ish (he doesn't swear, which is nice, frankly) and ...well, it's funny and fun, as much as taking apart broken engines can be. He's a big Miata guy and doesn't think highly of EJ-series engines...but he's never been able to get his hands on an H-6 until now. (And yes he's got a bunch of EJs on his channel)
And to head off the "wtf" of some of the things he does He won't sell rubber hoses; he says you should always buy new ones. Early on in his channel he would cut them and people in the comments complained. So he started removing the hoses...THEN cutting them. He won't sell used water pumps. He junks them. People complained. So he started getting really drawn out on how he would dispose of them. Sometimes he lets the schtick slide, sometimes he will do a 5 minute bit on saving it only for it to be crushed later. There's a few other things in there similar to that...things you shouldn't re-use he'll make a point of disabling or destroying, usually.
