If the flywheel was all he destroyed, he was extremely lucky. The hydrolock damage that I've seen was mostly internal, including things like bent rods, or rods tossed through the side of the block.

Then I will finally get it to start and turn over if the starter and flywheel match up for long enough, but it will soon die, acts like it is being starved of fuel. After doing this a couple times it will start right up, run at high rpms for about 3 minutes, then go to low rpms and run like a champ. Once I have done this it will start right up every time.

I havent dug into it yet but since it seems like multiple problems im sure I will have to dig into the starter and see if im getting air in the fuel system somehwere.

Has anyone ran into anything like this?

Yeah, my truck is doing something similar. The grinding on mine is infrequent enough (like once a month in daily usage) for me to forget about it and never get around to diagnosing it. The start/die issue is a problem, because on cold days, I can drain the batteries before it'll re-fire and stay going, so I have to jump the truck.

I'll get around to diagnosing this stuff, um, when I get to it. I did find that it's not hard to jump the CUCV from a 12v car, just connect the 12v car battery to the second battery for 30 seconds or so, then the first battery, then crank. It'll dies pretty quick, and I'd skip the glow plugs, just use starting fluid. Oh, and that's how I mitigate the other issue too, the starting fluid can keep it going long enough for good fuel delivery to occur. Just don't mix starting fluid with glow plugs.

High idle/low idle is perfectly normal.
