Lack of oil . Engine was about to seize or started to. The rotors are not salvageable. When the oil is not there to keep them cool they expand and the side seals are toast. The side plates may be beyond repair also , lapping them may save them but the hardening may have been damaged leaving only soft metal.

Best to find a new block.

I agree. About the best that can be kept out of this is the rotor housings, possibly.

Yeah I think we all agree on that, but what I'm curious about now is what caused the lack of oil and why? The motor was rebuild with all new internals including all new seals all new bearings and a new pump, but it seems that the problem started with coolant mixing with the oil, which then resulted in the failure you see now. I'm think it was this mixture of the coolant with the oil that did her in, so to speak. I could be wrong though.

That's good i9fd3 and I will double check that, but I'm almost certain that was not missing when I opened it up.

Yep, either that or a problem w/ an outer water jacket o-ring during assembly or a cracked or broken outer water jacket o-ring land at the bottom of one of the irons that'd lead water to drip into the pan..
