Thread: Water Proofing a V8 rangie?

a. Make sure your ignition system is in really good condition.
Old leads tend to cross fire and arc and old plugs draw more current so it causes the leads to cross fire and arc.

b. You can use silicon spray or wax type spray or Lanotech for a temporary way to make the leads water resistant but for a more permanant fix you can use battery spray, I suggest you use the transparent type that Wurth sell or there is a product called Liquid rubber or something like that from Momar which is fantastic but costs $40 a can and I use it on the spray units all the time.

I have seen heaps of fancy tricks to make petrol engines water proof but the main thing is to use the best quality leads with good tight fitting plugs, a good quality cap with an O ring under it and a good coil, new plugs and make sure you keep it all up to service and even just a spray of WD40 before you go out makes a huge difference.

If you were to go the pump air into the dizzy etc you would need to have to use a compressor, reciever and pressure regulator and still there are no guarenties but you can always try it if you want.

How old is all the electrics??
Leads / Cap / ect

Is it still running points??

Just seen mcrovers response ... Not much add to the list other than spray WD40 inside the dizzy cap
Someone else has tried "Antifog" .... to keep condensation from forming inside the cap when being hit with cold water outside

I'm running a 3.9 Disco block with the old cover off the 3.5 fitted to it with SU carbs. I have fitted the electronic ignition from the 1996 Disco. All leads are new 8mm. The plugs get changed every 6 months.The coil is new as well. I have a snorkel fitted with a sealed air box set up.I am still running the large steel fan.The truck also has LPG, petrol dual fuel system fitted.

Do all of the above .... Plus ... On the dizzy is the module block (unless it is remote hooked near the air cleaner) .. make sure it's seal it up with silicon or Sicaflex ... use some electrical grease inside the connecting plug .. to keep water from seeping into the pins inside and shorting it out and check where the wires enter the connecting plug is sealed

Eleco grease and lanolin (Wool Grease) is good . I submerged my rangie wile crossing a Inland lake on an Island and it kept going Water even came through the vents. Stuffed the soundsystem and carpets Also stuffed my wifes hand bag as it was sitting under the vent We all had a good chuckle over the CDs floating around on the floor

Has anyone tried a pipe from the heater and pumping hot air into the dizzy cap? Do you think this could work? I have an old dizzy body here and have seen the drain holes in the bottom. If I blow hot air in the cap, the air pressure should keep the steam and water out. What do you Guy's think?

The heater would not pressurize a match box let alone a dizzy If playing in H20 Some just block Drain holes. As my old mud racer had. It never got wet. Keep drain hole and a small air compressor sounds good but I have never bothered. More to go wrong

You could try a gaurd underneath to stop water getting picked up by the fan.
