Would'nt the pistons need removed to get rid of the ridge?I've never done it before. Sorry to hi-jack the post,in the same boat kinda.




not necessarily , it just needs to be clear of the reamer . Yes it has to be removed , but as said if you have a big ridge then you need to look at other things like bore taper , cylinder roundness ... The ring needs to seal for 100% of its travel , not just at the top.

I'll bet at least one of out shadetrees has removed the ridge on a block they never disassembled
