Pictures or not, the motor needs to be pulled and EVERYTHING checked. Running that much bearing material through it has trashed every bearing and bearing surface so they need to be cleaned up.
Blowing out bearings has he did sounds like there was some severe detonation under load and the bearings were simply pounded out. There is no doubt in my mind that there are a couple of egg shaped connecting rods in the pile.
I think you need to just let it go. It's obvious these two guys don't need anyones help or advice and they will just do what they gotta do anyway. Leave them to their own devices and they'll get tired of f'n with it...
