The floors look OK. They'll clean up reasonably easily.



I got some help with a hose to try and find out where the water is coming in. My first suspicion of the top of the windscreen seems to be incorrect. Hosing down that spot doesn't seem to lead to water coming in. The A-pillar under the plastic cover is dry, and it doesn't run down the side wall. Spraying at the bottom of the windscreen and filling the plenum does result in water coming in on the passenger side. It drips down around the heater fan. It seems to me that the plenum fills up and it leaks in behind the bit above near the bolt on the top right of the next pic. At first I thought it was that middle bolt but the water level seems to stay above that. The plenum drain hole appears to be clear.



I need to spend a bit of time just confirming things. I couldn't get water to come into the drivers footwell with the hose. From the look of it, it might be the door seals. It wasn't as wet nor as rusty as the passenger side.

It's all way more than I'd hoped to do, but best to get it right. I'm still having fun too. Incidentally, my kid locked the doors with the central locking and I tried to open the rear (boot) door with the door locked. Now I can't open it at all, inside or out with the lock open. Any tips on this? I imagine it's going to involve pulling the skin off the back. Annoying because the back is full of front seats etc!

Cram a timber wedge in the top corner of your door to get it open 1/4 inch, get a coat hanger and fish away! I reckon you could get the back doors hinges off through the gap between the front and back doors if you really had too.
If you get sound proofing/insulation i went for ping jing half the price and twice as thick as carbuilder dynamat.
Cheers Jim

I can reach the rear door lock and open/close it no worries. Feels and sounds fine. Pulling on the inside patch does nothing. Squeezing the outside patch feels spongey and does nothing. Feels like it's hung up on something. I think I'll have to get the stuff out over the back seat and remove the door card to sort it out. Hopefully it's just an adjustment thing and not a worn out thing

Also recommend you check if the heater unit is leaking. Because they are full of water all the time, they can rust and fill with gunk.
As I mentioned, ours started leaking out the back of Quilpie on a trip, so my BIL the mechanic just bypassed the heater completely. It's a temporary fix until getting a replacement heater.

was a temporary fix on mine as well. that was 3 years ago.

re: the rear door, have you tried locking-unlocking with the key too?
Give it a few unlock/lock/unlock cycles.
I haven't see how it's setup, but the D2 rear lock can put itself into this no mans land situation where it's half locked/unlocked in some internal lever or mechanism.
Sounds like this may have happened to yours too.

Hi Poida4x4

Should have bought mine, the floor is already coated in three coats of POR15 and two coats of spray on body deadener and it's the same colour.

Make sure you use a rust convertor like "rust buster" from bunnings and then paint it before putting down any 4x4 insulation or similar. Depends on how long you plan on keeping the vehicle as to how much time and money you spend. I was going to keep mine for years so I went all out and did the whole floor front to back. Have done the same to my 200tdi Disco.

As for the rear door

There is a spring in there that plays up. It is a fiddly job to repair but a cheap one. Do a search for it on here, I seem to think that someone did a thread on how to replace it.
To get it open try inserting the key turn and hold it and at the same time lift the handle. That is how I have to open the door on mine.

Good luck with the Disco

P.S. Mine might be good for parts

Yours did sound good Neale, but this one was all ready to go. I probably couldn't lose either way.

I sealed up the suspected leak spots today and cleaned up the floor ready for paint. I'll test again for leaks tomorrow and if there aren't any, I'll get painting (Penetrol and appropriate paint). Incidentally, when I unlocked the car to start all this I tried the rear door and it popped right open. I'll plan to have a look at the mechanism some time, but I probably won't until it causes more trouble, most likely at a really bad time.

Oil the door lock?

Well my sealing didn't work. I was close to working out the problem, but didn't quite nail it. There's some sort of intake under the scuttle board that's above the plenum drain. I thought the water was pooling too high in the plenum and leaking through where this intake contacts the plenum, but when running water down the windscreen quite a bit of water comes out underneath the plenum, coming down the windscreen side somehow rather than over the scuttle board and into the drain. When I stuck my hand up there water was flowing right into this intake. My plan now is to try to seal the rubber/scuttle contact point along the bottom of the windscreen, and that bit where the scuttle board intersects with the lateral bits of scuttle board. A bit annoying, but it's good to have a better idea of the problem.

EDIT: Here's a pic from a Disco 2 that shows the intake I'm talking about. I think I'm on the right track



I've heard mention of a RAVE CD-Rom or something that might be like a Landy manual with exploded diagrams and stuff. Is that right?

EDIT: I also think I've got the terms "plenum" and "scuttle" the wrong way around.
