I have 86mm Manley Pistons. They use Manley part number 46860-4 rings. Total seal supplies the rings for Manley.
(86mm bore, 1st 1.2mm, 2nd 1.2mm, oil 2.8mm)
After 1200 miles on a fresh rebuild most of my crosshatching has been wiped off my cylinders. My main bearings were fowled up a bit with debris and the head gasket had a coolant leak.
My block is back at the machine shop getting redecked and rehoned. My crank is getting polished the block will be boiled and cleaned.
Although there doesn't seem to be a lot of info, I have read that some people dislike total seal rings because they are harsh on Mitsubishi cylinder walls. On closer inspection of the rings, only a very tiny line in the center of the rings outer edge ever came in contact with the wall.
I was planning to get npr rings and call it a day, however my pistons don't use the stock size rings.
Mahle 8600ms-12 and JE JC0004-3386 are the only two sets I have found containing the right size rings.
I don't want to open this engine up again. How do I choose the best ring set? Are there other Ring sets available that I was not able to find?
