speaking to a guy at a punch challenge on sunday about waterproofing the v8,and he came up with a possible solution that was featured in a magazine a few years back

what it involves doing is running some airline from the arb compressor via a seperate switch and one way valve
and plumbing this into the dizzy cap,when you go into water you allow air into the cap thus preventing water from getting in

sounds like it could work so do i give it a go?:beer2:

Don't know about the switching or valves although it sounds complicated for the job in question. Otherwise I would expect the pump would need to be running constantly when you wanted protection.

You would need an in valve at the top then an out valve at the bottom. If the cap was sealed it would just blow up.

It's pointless because what would it do exactly? You'd still seal the cap anyway so it's just blowing air out for no reason. I really can't see the point at all.

Anyone ever thought about filling the distributer with something like mineral oil? That would work but even then, it would have to be sealed to keep the oil in so you're back to square one.

Best way I have fond to waterproof a V8 dizzy is with a couple of latex gloves and some cable ties.

doesn't need to be sealed at all, as long as you can keep the air going in at the same rate as it's coming out. it will then be under positive pressure and prevent water going in.

However, would need to be able to cope with differing pressures, when the water is splashing and surging about in the engine bay, it will have more pressure behind it to overcome the air pressure inside the distributor cap.

think the latex glove and cable tie route is preferable myself.

Stick a few condoms over it, I've seen a RR go underwater with only condoms and Tupperware for waterproofing.

The only prob I had with my old V8 was when wading the belts used to throw water on my dizzy , until I made my own splash guard , never had a prob after that . ( never went deeper than just over the wheels stood still mind ) .

the old old way was to add a small pipe in the side of the dizzy and stick it on the intake this will give a small vac witch would suck any water that did get into the dizzy into the manifold....
