I got my engine with transmission and transfer case from Soshin Trade Group or Soshin USA. I found it with a "Mitsubishi diesel" ebay search. It's funny, they have two different web pages, slightly different names, but the same address:

They were good to deal with. They seemed knowledgeable. I paid with PayPal and had the engine about four days later.

The engine seems a little beat up. The oil pan and some other steel parts were rusty. The aluminum parts had white fuzzy stuff. The timing cover had a broken tab. The coolant passages were full of brown sludge. The engine oil was very dark, but you expect that in a diesel. I am hoping the rings and the valves are good. I'll know when I do a compression test.

I wonder what the engine came out of. I wonder what the PTO was used for. It may have run a hydraulic pump or a winch.
