So I stripped my crank case drain plug (threads came out with bolt). I drilled it out and heli coiled it (perma coil actually) I set the threads about a turn or two in from the bottom of the case so my drain plug wouldn't hit the threads. I got a crush washer from napa, and it's a thing copper one. Would the thicker aluminum one work better, the kind from the the dealershiip?
Did not use locktite on perma coil. can always remove and and reinstall with locktite. If I do that, do i apply locktite all around the insert? Hopefully just a more robust crush washer will take care of the slow leak.
