Thread: Water Crossings & V8 4.0ltr 2004 Discovery.

It should go like a submarine with no distributor to stop it!
The only area of concern would be the plug leads, particularly where they meet the boots and the boots on the plugs. Put some Dielectric grease around the joins and you should be able to go underwater. If you ever got to the coils you deserve the engine to stop.

I have always found my V8s to be great in water. I have gone through water over a metre deep and that was in a 77 with only a Luminition and no snorkel. It also stalled at the last obstacle in the Nissan Trials dam, which was over the bonnet in one corner , but restarted and I was able to back out. So the points were always the greatest cause of the "V8s don't like water brigade"
So just how deep do you want to go???

The stuff you have mentioned it defiantly to my extreme. I would generally go half door height would be high enough.

The grease around where the leads meet the plugs. I will have a look at that. Thanks.

I would suggest you move your ECU which sits under your passenger side seat if I'm right. Driving steadily through water at half door height should not be too much trouble but if you stop for any other reason, then I would expect some water in the doors pretty quick - unless your seals are better than mine - i'm still trying to find the best way to seal my doors up to window height at least :roll:
You might want to move your diff breathers a bit higher as well.

Good luck, Mick

Yep totally agree. Why did I fixate on the motor only. If the Disco 11 has the same system as the old Rangie Classic, and I think it has, you can get a much better result with the door seals if you get one from a wrecker and cut pieces to fit between the two slots, and superglue them to delete the slots. I have done this with all four doors.
I recently went through about 60cm-70CM of water without a drop in. The other thing to check is that the plastic seals behind the trims are a complete seal. I found mine had not been glued properly after some dealer idiot had presumably replaced the central locks.
You may have to cut some holes in the rubber to let the air out as you close the doors as that is what the slots are for.
The ECU has a rubber O ring seal to theoretically keep the water out but I once spent several happy hours with a coleman lamp and matress inflator drying out an ECU. The car went after it was dried!!!

Thanks Phil,

Having had floods here last week and having spent several hours in deep water, the cabin didn't even come into the equation,

mind you, I didn't get out, just took the pix for the media,

no water interior....as i mentioned elsewhere, the PAS was a bit sus, but ultimately sorted, this disco makes fair submarine, wish i had a sunroof.....


by the way, the plimsol line on a D1 is the rubber strip along the sides, about 60cm from road, just keep the donk running, cause the tailpipe is much lower


but the interior was as dry as a.... um.....errr.....camels breath

cheers, GQ

I have since found that the air cleaner holder box where the paper element is kept dose not seal properly at the rear corner where the hose continues to the motor. It lets in water and I have seen the same problem on a friends D2.

Has anyone else with a D2 noticed the same problem and what did you do to rectify it.

I know this is an old post, but did you find a solution to the leaky air filter box? i noticed i have been leaking in there too, not much but enough to worry me. I was thinking a bit of duct tape around the seal might help?

Would certainly do the trick I think. Forgot about this post Craig so sorry for ignoring you. I ended up fitting some adhesive foam round the adges of the air box and to date this has sealed it pretty well. I have not done any deep water crossings since and try to now stay away from the water if I can but time will tell if it works.
