Rear Main Seal

The IF is the issue... I am about 50-50 with rope seals ... I guess that is better than 0-100, but I suspect a child could do better LOL

The only rear seals I have had 100% success with are the full circular seals in some other engines.

That's because the full circular (one piece) seals aren't affected by line honing.

50/50 isn't bad. I know guys who are O'fer on them and won't even look at them.
