Figured it coulda looked worse, but I sure don’t know. Bores could use a hone or more, look like a bad mirror finish but no other marks either.
Some rod bearings worn down thru to the copper.
Also some weird green discoloration on the rod there not sure what that’s about.
Looks like we got ourselves a good old F big 3 little 4 piston. I suppose that means they are standard size?
Thrust bearing there looking ready to be replaced, I assume?
Heading to the shop to get it checked out for real, will see how to proceed from there.
