Thanks for all the encouragement. I'm not keeping this engine anyway, so it's not the end of the world if it stays frozen. Just don't want to sell it at a frozen engine price if I don't have to.

I'll pull the heads and look at the cylinder walls, let you know what I see.

Meanwhile, I don't see any evidence of excess heat at the exhaust ports. Manifolds are not present, so can't look for cracks or discoloration there.

Obviously there would be valve train problems if it ran out of oil running, but the pushrods are all straight. There are no shavings or metal pieces in the oil pan. Would the chambers/cylinders/valve seats tell me anything about overheating?

I'm still under the impression this is an okay engine that got a little water inside it while dry.

Thanks,

David
