Hi all

This is a job I have been putting off for a while, but with the heavy rain today I was getting a wet foot while driving, so I need to remove the dash to see where the rain is coming in, and to repair a couple of holes that I can see.

How easy is it to remove the dashboard? What do I have to remove to get access to the bulkhead from the inside?

Cheers

before stripping the entire dash out, check these areas.

outside on bulkhead below windscreen, there should be 2 rubber buffers that the bonnet rear edge butts against, if these are missing water can get into the cab more here

remove fusebox cover, pull back mat from the sides there should be 2 oval rubber grommets [one each side] replace if missing or ripped/punctured item 5 page 750

there should be a rubber gasket around the holes where the clutch & brake pedal units come in to the cab make sure these are intact or use a suitable sealaant between the pedal box units & bulkhead. clutch item 13 on page 476 & brake item 10 on page 478

Mine also leaks through the windscreen rubber and this trickles in and then down into the footwell giving the impression the leak is lower down.

Cheers for all that info, that is very helpfull. I think I see the problem now though. Where the channel behind the bonnet lets water run off the side, it goes down the joint between the wing and the bulkhead and down the side of the footwell. There is a pretty big hole there which is probably where the water is coming in. It then runs along the plastic under the dash and onto my foot. Wing off as well as dash out I think.

I also want to get to some holes on the inside in the top corners by the windscreen hinge bolt holes. Usually this is on the outside, but not on mine!

Teti did this job in the last two weeks, before fitting new carpets wanted to find out where the water was getting in so stripped the cab back to bare, seats dashboard the lot. The full dashboard can be taken off in a morning. Im glad i did it as i could see water trails that would have been hidden. Also allowed me to hammerite any rust that the water ingress had causedmy grommets were ok but the one in the passengers footwell was missing. but it turns out my watter was coming from bad seals on the windscreen vents. 11 replaced them and IM DRY NOW

There is a Tech Guide about how to remedy leaks on landroverweb.com

Hope this link works:

Defender Water Ingress Manual


Need to sort a few leeks on mine before i bother fitting any sort of interior. Went round a corner earlier today and literally got rained on from the top of the door... :)

if you want to get dash off grab the instructions from the LR radio fitting kit, lots of piccies and straightforward.

If you can't find one pm me and i'll do a dig and scan it for you

That is why I have put it off soo long. A friend has a 54 plate 110, top of the range spec, ex demo vehicle and that leaks too. Not as bad, but still a wet foot on occasion.

I am sure they must have a part number for a water leak, same as they have for oil...

The only leaks left in my 90 are the footwells, I'm 99% sure it's coming from the windscreen seal (badly perished at the corners like they do) and the windscreen hinge bolts (the gaskets for those have long perished too).

The plan is to have it all off when I get a chance and replace them both, plus the screen-to-bulkhead seal, and hopefully that'll see me dry in the rain!

I thought my leak was from a perished windscreen seal until I had a new windscreen and seal fitted. The leak must be from somewhere else. I also have looked at the ingress manual which is of some help. Luckily it doesn't rain much here :rolleyes:

I had a leak earlier this year, which I thought was coming from the bulkhead. Eventually traced it to the throttle cable, a grommet was missing, but an easy fix nonetheless.

I'm lacking those rubber buffers too. It seems I cannot find their p/n in my parts book. Anybody has it handy?

On my phone I can't make head nor tail out of that picture ?

 I have an oven with a 'stop time' button. It's probably meant to be 'stop timer' but I don't touch it, just in case.
