Hey, i was checken under my hood the other day, and i noticed a samll 1/2' inch crack in my distributor cap right on the front side. Its pretty much new so i dont know how it got craked. It looks like it my be letting in moistur making it a little foggy inside. i dont think i have a gasket on it so maybe that caused it?? well anyway i was wondering if i should replace it or if it will be ok?
