mmm..just shows different schools of thought. I never use any sealant on any engine case or covers of any bike motor unless it came sealed from the factory that way in the first place. A nice new gasket, clean dry surfaces, a smear of clean oil to get the swelling happening, tighten it up evenly and Bob's ya Uncle
in an emergency I may use 3 Bond but very sparingly and I actually don't remember the last time..the tube I have is still marked with a $42 price sticker, I bought it back in about 1980 so God knows how much the stuff is worth nowday
