Re: amc 20 cover gasket
Next time you have the cover off drill and tap a hole in the bottom of the housing, and then clean the chips out. Stick an allen-head pipe plug in and you'll have your drain.
You'll probably have to make a rubber gasket. A parts house should have sheets of rubber gasket material. Just use a paper gasket as a template. Cut it carefully with a razor blade, and make the bolt holes with a paper punch.
You should also find out how water is getting into the housing. Is the vent line sound and run up high somewhere? I tied all the case vents into a hose inside the frame rail and ran it up to the air cleaner housing.
