I've been checking this site out lately. I've ordered a couple of smaller things from him. I've got two 300SD Mercedes. One is a driver the other could be a donor. I'd like to put an OM617 in the YJ that's stashed in my barn.

Filling the crankcase that full of diesel will wash the oil from the bearings. It doesn't sound like a bad idea for cleaning the crankcase. You would want to pressurize the lubricating system with oil prior to starting.
Prelubricating the oil system is not a bad idea under any circumstance.
Get a case of brake clean put the engine right side up. Spray the whole inside of the bottom from every angle imaginable. Better put your hazmat suit on you'll be wearing it.
The pan cutting would leave that kind of residue. And that's what it looks like now that you mention it. Maybe clean her out whit a bunch of brake clean, look at a rod and main bearing and see what they look like. If they look good it might be good to go
It definitely requires further inspection. If it was my engine I'd be having the sinking oh sh** feeling about now.
There shouldn't be anything like that in a new motor.
I guess you could pull one main and rod cap and see what it looks like. Could the grit possibly from rust caused by moisture/condensation? Perhaps the engine sat in an area with high humidity. It's amazing how nasty things can get when left for a while.
My experience with that approach is if it broke because of over torquing that will probably work. If it broke because it seized going in or out that will probably not work.
On the other hand, he might not have sold the engine if the bolt had not been broken in the crankshaft. The worst thing that could happen is you swap crankshafts.
I've tried recirculating with a pump, maybe I'll try that again.
My most recent attempt was putting 5 gallons of RUG in the bottom of a 55-gallon barrel and allowing the oil from the centrifuge to drip into the barrel. When the barrel was about 50% full I put a 1/2" pipe with an agricultural...
The only problem with that thought is there aren't too many engines as old as these with a lot of life left in them. Maybe sleave the cylinder and do a rebuild
I'm glad you have it worked out.
I've driven 2000-3000 miles on a combination of WATF and WMO (0/20, 5/20, AND 5/30)with no problems. I'm also using it in my old tractors. The only issue I have right now is I'm centrifuging more oil then I'm using.
