Best way to prepare a V8 for a water crossing is plan a differnet route...

Perhaps take some jerry cans incase its a long way round

What about the plug wires getting wet and shorting. That rubber for the distributor is a joke. You can use electrical silicon( It's special keeps water out and allow electric to flow) and seal the distributor but it's the condensation inside the rotor that gets you. WD-40 is the best thing to carry with you and when it quits just spray everthing with wd40 dry the inside of cap out and spray then on your way.

Now if you wanted a system for that then find a mod conversion for it?
Where to look your guess is as good as mine

Hi, some advice from some experienced guys who did one of the longest land trips in a land rover series many years ago comes to mind. Remove or disable the fan! I would fit electric fans and then you can switch them off, but then again they may not work once full of water!
General advice - Fit wading plugs to bell housing and timing belt housing (for diesel). Grease all grease points profusely before departure. Check all vent hoses are sound and attached high enough (axel and gearbox vent lines). Wait for car to cool down after a long drive before entering water. (This is to allow the air in the axles etc to cool and contract, as when you drive in the water it will cool quickly creating a vacuum and sucking in water past seals, ask any boat trailer owner how long their bearings last)
After coming out of the water remove wading plugs and spray everywhere liberally with WD40, especially ignition leads and plugs, but also hubs (not discs) and around the steering box input and output shafts.
Good luck!

Have had the same bearings in the trailer for 5yrs so whats the problem??? We use what is called bearing buddies, Metal bearing caps with a grease fitting in them has a spring loaded plunger inside it keep it full of grease and it pushes out the water. In and out of water about 120 times a year

And what the feeck does wd40 do for steering box input and out put shafts they have seals and if they don't leak sterring grease/fluid ????????? And the hubs they also have seals ????????? Wd40 disperses water not water proof things

Watch the top gear Bolivia special where Clarkson uses a load of Vaseline

also, land rover series training video from the 70s says to loosen the fan belt immediately before crossing and do it up again afterwards. Not much use with an electric fan. make sure you've got your bell housing and timing case plugs screwed in too

Hi mister helpful, the LR Disco does not have bearing buddies which keep the grease under pressure, so when the hubs cool the grease fills the void left by air, or the spring pressure keeps the hub full of grease at all times, (although unless you assembled the hub in a vacuum there will be air in there).

The water displacing fluid (WD) does exactly that, when you eventually have to replace your steering box you will find that the output shaft has corrosion around it where water has got trapped between the seal and shaft unless it has never got wet or you have kept it greased. Same applies to input shaft seal, if you you are going that deep into water that these parts will be submerged, I recommend that you give them a squirt afterwards to remove the water and thus help prevent corrosion. I have owned boats for years and and regular maintenance sprays with WD keep the trailers and engines in tip top condition. But this is just free advice from a very experienced Land Rover and boat owner, do it your way if you like. Just one more thing, WD fluid is also used on aircraft as part of the maintenance program to prevent corrosion, if its good enough for Boeing and Airbus, I think it should suffice for a Land Rover.
