when bangs and pushes oil passed the rings

I was told years ago that 10 thou. wear was the absolute max that was allowed for a re-ring job.Measure the bore at the top and the very bottom and that should get you the standard bore. Then measure the bore just under the ring groove where the rings turn around and see how much wear is in this area and also measure how much out of round there is. Nice new perfect rings won't seal in old out of round worn out holes. Also check pistons for ring land wear and the skirts for wear. If you re-ring be sure to cut the ridge completely out and hone and do a nice job in this area so you don't break the new rings.

If the sleeve is not worn too much, be sure to check the top of the sleeve and make sure that the top lip were the head gasket fits around is not burned away. The 830 I own that my Uncle owned had the tops of the 2 inside sleeves almost completly gone on one side and had to replace them.
