    I have a FAST duel sinc in my BBC, I get moisture in the cap a lot.
    I spray it with WD40 but dont last long, If I do not clean out the moisure all the time then the cap terminals get burned and these caps I can only find from FAST are about 35 bucks.. ouch!
    I read about drilling vent holes or does anyone sell a vented cap.

    Some people have luck with sealing the caps on using a soft silicone sealer. Don't use a harder RTV or you may not be able to remove the cap without damage.
