Wasn't trying to offend anyone guys. I took it as though the poster must have had very sallow threaded holes in the cover rail, and with the compression of the gasket it would be impossible to compress the gasket before bottoming out with the 1/4 inch engagement rule to take effect with that depth. I didn't mean to give you a wedgey dude!!! I didn't think engagement had anything to do with proper thread depth to compress the gasket.
