Thread: Waterproof your V8's Ignition

I have a Disco 1 rear mudflap cable tied in front of my distributor. That cured 99% of my water induced missfires.

AFAIK, he had to get a family member to post one out and it solved all his wet-weather sputtering - to - a - stop that plagued Minis over here.

There were a few different types. The ones I have are:
- a hard plastic condom that fits over the distributor cap.
- a plastic shield that clips on the distributor
- a plastic shield that clips on the motor and shields the distributor, coil and generator.
I have examples if these three types.

They were probably options and so not a common item but were available in Australia.

I had one of those rubber things in my distributor. The only thing it did was, when water got in, the rubber cap kept it in.

The best system I've seen is the two nipples installed on the distributor as shown in one of the previous posts. One of the nipples is connected to the vacuum on the inlet manifold to keep a constant supply if air flowing through the distributor. The other nipple was connected to a tube that ran up under the dash to make sure the air flowing through the distributor was clean and dry.
