    Waterproof Distributor

    Gday just wondering if anyone has a permanent solution to waterproof your distributor. Im over spraying on WD-40 all the time.

    Sorry couldn't help myself, its been so long I can barely remember what a Dizzy looks like. I am sure someone will come along with some info that is actually useful

    Cheers Andrew
    Why would I buy something for $10 when I can make it for $20

    Reminds me of another time when for an anti theft device before we had immobilisers, I would pull the rotor button (was that what it was called?) out of the dizzy and pop it into the air filter box for storage-when parking in the city etc so the panel van was not stolen.

    You could try getting some silicone grease, this is what the car manufacturers use in connections that need to be water proofed. Smear it all over the ends of the plug leads and push them on/in, and around the lip of the dizzy cap might help, otherwise good old silicone sealant will do the job, although a lot less serviceable.

    Other than new leads/new cap and high temp grease or silicone grease where the cap mates with the distributor.

    Over time the rubber plug caps on the ends of leads stretch and allow water to wick into the top of the cap and short.

    I used a paint on gasket stuff for aircraft on my old GQ it was a bit like latex to apply and was easy enough to brake the seal when I needed to check inside left a little bit of mess but easy to clean off and re seal from memory I got it from bursons auto

    People used rubber gloves on 4 cyl. vehicles when I was growing up. Don't know haw they fixed anything else, except slop lots of grease or silastic around joints and gaps.
    I think electrical tape was part of the fix too. Could have been self amalgamating tape instead though.
    Morris mini's and Austin Front WD's were renowned for stopping when driving through puddles.

    On my VW Baja I had a silicon cap/sleeve that covered the top and bottom of the dizzy and the leads. It was a tight fit. I had it sitting in hot water to soften it up before fitting it. Having the engine exposed it was always in the rain and elements. Even crossing rivers it was fine.

    It looked like a rubber sock.

    Cheers
