Last time I did a ring job without reboring the block I got a set with a stepped top/compression ring so that it did not interfere with the edge of the unworn top portion of the bore.  Best to avoid hitting the hard steely bits with the brittle rings...

I think you can get a tool to ream the edge down as well. Never done it though. Needs an experienced eye to decide where on the scale of "slap some new rings in and hope for the best"  to "full rebuild" we are. :-/

Sounds like the former option was probably taken!  No doubt we will find out in due course....   Best of luck james...  8-)

Cheers Broocie

I'm thinking of taking the easy way out - take the engine out, and give the block to the machine shop  ::)

The guy there is very good, he will welcome me in and talk me through the lot, probably a worthwhile learning experience, while getting a full rebuild at the same time  :y

Sounds like a good plan. You have the fun part of doing the rebuild but knowing that you've made the right decisions, assuming the guy knows his onions.

Hmmmm.....the bores are easy to check and Vx engines rarely suffer bore wear.

The piston ring grooves are also easy to check plus fit the rings into the bores first to check the gap size (I buy over size rings and grind them back).

A light hone can be done with wet and dry.

The key thing to do is inspect the bores.
