I got the correct rings in yesterday and went to fit and assemble today. It appears that the machine shop messed up doing the bores and oversized them too much. I'm checking further, but I'm going to talk to the shop on Monday and see what happened. The piston to bore clearance is fishy in my book becuase the end gaps on the new rings is still past the service limit in my manual.



The rings fit, but not with the bore size the block had. You also wanted to build the skirt thickness up by sending them to Terry. Maybe I'm misunderstanding what took place, but I've gone over our PM's to double check and that is what I've come up with.
