I'll give it a shot and see what is going on. What are the chances of a really worn upper rod bearing?
When I had the rod bearings out, I pulled and pushed on the free rods but I could not feel any play.
The pistons though at bottm dead, when I pushed on them they moved back and forth ( like rocking ) in the bore. Not sure how much is too much.
If anything, I think I will have to pull the engine and take it apart.
