I don't think the "angle grinder" cut in the crank case is a problem Ken. I have had a look at my engine and it has the same machining mark. It's a polished engine rather than a black one so maybe doesn't show up as well, I never noticed it until you mentioned it. I have no leaks from that area though.
Yeah...I wasn’t clear then. No leak there. The 1/2” bolt forward of thetecwas wet around the bolt. That “slice” just surprised me. You have it too? Strange. Wonder why.
