My buddy’s and I have this discussion often. Years ago we tried sealer and gaskets but if you race like we do the gaskets will squeeze out leading to a worse leak. I use Ultra Grey and get three year’s average out of it. It’s a job I’ve done at the track but like most maintenance would prefer to do at home. I have one of Andy’s 1/2 inch engine plates I’d like to switch to instead of this cheap azz 1/4 inch plate but again winter job because I want to change my transmission mount set up too.
