So a change of plans, While I still need to disassemble the engine, think I would be wiser to spend some time and see if can get it un-stuck first.
The cyl photo is the worst 2, I think they will clean up.
The last photo is where I think most of problem will be, crusty push rods from mouse pee. But there is only 2 or 3 that look bad. But cleaning up.
New plan is to leave the pan on, acetone/atf, diesel clean and soak everything.
Wash it all down into the pan.
Then actually put a breaker bar on it and see if it will turn. Only attempt to turn it over so far is by hand grabbing the crank pulley.
Starting to think if I get it unstuck, and cleaned up, it would probably run.
Assuming it does not have bad bearings/crank
