Waterproofing a 3.5 V8??? any clues

[discorich]

One of my mates has just got a 3.5 V8 carbs and was wondering what is the best way to waterproof the electrics so that he can go play. The disco has been off roaded in the past but it tended to avoid water, but he is wanting to follow me in my 200tdi what loves to go into deep ponds and the such.

Any help would be appriciated.

allegedly if you make a hole in the disy cap and connect an air supply to it then that  will provide possitive pressure to displace water. also a smear of grease on the plug/ht lead rubber caps is meant to help too. having said that tho my mav was petrol and i had water upto the wing mirrors with no mods or probs on several occasions, you just needed to keep moving forwards.

vasaline works better and less conductive according to the orical buldog

i used a 500ml pop bottle with the bottom cut off over the coil, then siliconed it on and siliconed the lead through the top, then cut a big flap out the side of a 3litre squash bottle and zip tied ir around the dizzy as a splash guard, sounds abit micky mouse but it works!

i cut up a 5 litre plastic can and put it over the dizzy, this stopped the fan blowing water over the dizzy if water hit it, i later took the fan off and sorted out an electrical one, but fitting the plastic container stopped water splashing over the leads. I also fitted a drinks bottle over the coil which did the same thing, i didnt have any trouble in water after that, sounds daft but it worked

I am trying to waterproof my V8. Its a range engine which was converted into a 90. I been have problems with injector resistor pack filling up with water. Many friends of mine tell me to get rid of the v8 and go diesel but personally i like the V8. I was thinking of moving the coil into the cab and just extending the cables & then do the bottle trick on the dissy.

I used to put silicone grease (the type you get in a tube for lubricating the zips on drysuits) around the base of the dizzy cap and then use Holts Damp Start on the leads.
You lift the rubber boots off the dizzy cap but leave the leads connected, a good spray of Damp Start and then, while it's still wet, slide the boots back in place. This seals the boots to the leads & dizzy cap.
On my V6 90 I also made a guard that stopped the water from the fan hitting the dizzy and I had that up to the door cappings with no problems.  ;)

On the V8 waterproofed dizzy upgrades the most important mod is the drain holes at the bottom of the dizzy are ported with breather pipes into the raised breather(s) manifold or into standard aircleaner casing (to allow the unit to breath). The vacuum advance hose is T'd into the servo line. The cap is sealed with silicon. The points are often replaced with an electronic replacement. Well fitting quality HT leads are used.
The silly rubber glove caps and water bottle mods usually pay no heed to the two holes at the bottom of the dizzy and it those which let the water in the first place!

i found those trap more water inside from condensation than they keep out, if water gets in it cant dry out again

IIRC they also don't like oil or petrol as they start to disintegrate if you get it on them.
Unless they've changed the material they're made of since I last looked at them?
