i fought this for over a year - block sanded the covers, tried si gskts etc - very frustrating

- you can find my posts here from a yr ago with all the usual "suggested solutions"

eventually i tried a different used cover - solved

postmortem - the leaking cover was not "warped" but at bottom corner it did have a "difference from parallel level" at the lower corner, so it was not making full contact there

very curious ??????? - only solution to that is put on on a mill and have it planed flat - about $40 at my machinist
