Every time it rains I have trouble with mositure at the distributor. I have replaced it once but still have an issue. Is there a rubber O ring between the housing and the distributer cap that needs to be replaced. Dealer says there is on O ring, but it doesn't seem right that there be nothing between the two to make a seal.

There is a spray that can be used in the cap to dispell moisture. At the moment, I can't remember a brand name? I've seen several things used for that, not sure if recommended for that purpose.
