I've seen several and higher use engines have at least some wear in the bearing cap. These look like they just came out of the box. You're right though, I have no idea. That's just a guess. It's not a tree I can cut open and count the rings. At this point if I can just save the crank I'd be happy. Is cutting the rods an option so I can get the crank out and then drive the pistons one at a time to try to salvage the block? The valve lifters and cam shaft are out already. I think I have room to get in there with something to cut the rods off to free the crank.
