    So after spending two hours wiping water and mud out of the inside of my distributer while stuck out in the dunes this weekend I'm thinking maybe I'll take some steps to make it a bit more waterproof. Anybody have some good tips or ideas?

    silicone around the bottom of the cap, and on every wire boot. Its waterproof so where-ever you put it no water's coming in.

    On the wire boots too huh? Didn't think about that. You just put a bead around the bottom of the boots and then push them onto the cap?

    Well, coil-in-cap distributors are pretty waterproof. You just need to put a little dielectric grease around the coil cover and then on each plug wire. Then put a little around the base of the cap.

    If you have an external coil then you need to plug the hole in the bottom of the distributor. I usually just put a bolt through it.

    also remember, if you're gonna seal off the distributor, you will need to change your cap more often... they're vented (somewhat) for a reason. If it's sealed you can start to develop cracks and large carbon deposits in it.

    I would silicone the bottom of the cap. You can also get a plastic hair cover thing that ladies bath in to keep there hair dry. Cut 8 small holes and slide the plug wire through and zip tie at the base to keep water,dirt,mud ect...
    off the cap.

    HEI distributors aren't vented... there is a miniscule gap at the bottom but that's not enough to keep the ozone from hanging around. With the TBI distributors they moved the coil out and left a gaping hole in the bottom of the base so ozone could get out... get about three times the miles out of a cap and rotor... but I think I can tolerate $20 for a cap and rotor once in a while.

    40mph run at a 2' deep mudhole. Carb doesn't seem to be too happy now either so I gotta get after that too...
