xj40 front footwells full of water.
18.01.2010 at 15:39:29
 
Hi all
This problem has plagued me for ages. Where is the water coming from.
I have investigated all the usual places, are the windscreens on the xj40 prone to leeks.
I know someone said that it might be from the well under the wiper motor, but I have checked that out and dont believe it comes from there.
Is there anywhere I can take the car to have the screen sealed. My carpets etc have just been consigned to the skip.

Thanks in advance.
Regards
john

try bulkhead rusty, door seals u/s, heater radiator leaking(check if water tastes sweet or has a smell to it) and of course yer chamber by the wiper scuttle you mentioned..still may be blocked etc. Shocked

this seems like a nearly impossible problem, short of rebuild. i have tried so many times to fix. my bulkhead had only a very few small surface rust patches, not holes, which i have sanded down and waxoyled the whole visible area of bulkhead in the engine bay (looks ok, as its a black car). i have the two corners of bulkhead rusted on wheel arch side, by the bonnet latches, i have repaired these with polyester filler painted over. i don't even know how water would get to those places as its supposed to run around the edge of the engine bay, on the guttering. duck bill removed but it was never blocked in the first place. i waxoyled the seam of the bulk vertical to the sloping section in the scuttle. but there was never any visible rust or holes, just that primer grey coloured metal, looking in good shape. STILL WATER GETS INTO FOOTWELLS. admittedly maybe not as much as before, but i just cant believe it can still find its way in? its definitely rain water, as its only comes in when it rains, and doesn't smell of antifreeze.

the two drain pipes that go down either side of the tranny tunnel- have tried putting wire up there to probe for a blockage, but there isnt one! but then again there was no trace of any moisture there either? so unless theres a blockage far up inside the heater ducts somewhere?

only other thing i can do is blast the whole inner scuttle area with waxoyl multiple times and hope it will seal any perforations? but need to wait for summer for that area to be completely dry first.
but am pretty pee'd off with the whole thing.

This is exactly like mine. I have now given up, but simply try to keep the car covered. I remove the sound proofing and carpets when I am not using the car. The water is coming in somewhere above the gearbox tunnel and soaks the insulation which is a fantastic retainer of water. Must e the windscreen, ut does it really justify the expense?
...........tis a bugger!

well I have had everything done to my car to stop the water getting in. Bulkhead,heater matrix ,2 windscreens
(going for 3rd) air con pipes clear,door seals checked. and this car has no sunroof so not that.

but still water gets in somewhere


So I do the same and cover the top part of the car if I can't be bothered to put full cover on.

oh, yeh. forgot to mention, i have silicone sealed the bottom of the windscreen too. that must be 6-7 different actions to try resolved one problem.

maybe to cover the car is the only answer. you're right

Thanks for the latest replies. It seems everyone is as frustrated as I am. But I will still try to resolve the problem in the summer. If I happen on a magic formula I will let everyone know.
The latest weather forcast down here is heavy rain perhaps turning to snow, with that in mind, I have just covered the car with my extra large car cover bought from Lidl.
Anyway nice to be back in the forum talking to jag guys

i think it must be something to do with what the last poster says. my most recent action- i have removed sponges that live inside the pillar cavity, located directly behind the the fuseboxes, on both sides. they were both quite wet.
i think i will try removed the front wings and have a look whats going on behind there, as there is defo some water action going on somewhere in that region, but cant figure out how that gets in. hopefully all will be revealed

Ooooooh, I hope you're ready for what you'll find once the wings are off. From what little I know, you'll wish you hadn't...

Removing the wings is not nice as the bumper has to come off, the side mounts rot, the top bonnet buffer bolts rot and snap off, the inner wheel arch liners are a pain, the  bolt that holds the wing to the sill gets covered in crap so you have to wire brush until the bolt head can be found, mine did come out clean, remember there are 2 bolts on the a post.
Also the side repeaters are clipped in place but also have double sided gasket to stop ingress of water(what a bloody laugh)
Now it has been commented that they dont know how the water gets down behind the wing and cable entry, quite simple, when looking at the wing where it meets the base of the windscreen and the top of the front doors mirror area there is a large area that is open due to the pressings of the wing and the fact Jaguar thought we all park our cars on flat ground so all water would be directed away(how stupid of us not to relise this)
Having done the hide and seek on my Daimler 93 car i can confirm that in order to do the job correctly you have to be brutal to overcome the bad design, for those who want to keep there cars from becoming a gold fish bowl there is only one way to do it.
Strip both wings off, remove all carpets, if bulkhead is suspected then removal of everything from the bulkhead to the  front of the rear seats then check the front foot wells move fuse boxes clear to inspect behind, on 93 cars disconnect battery remove live supply from base of bulkhead connections, they melt during welding, don't ask, now at this point you are in the house or pub feeling etremely frustraited as you have 50% of the car littering the drive/garage/spare room wondering how it goes back together and why is there daylight showing in several areas.
To date i have  had welded the floors, cable entry and several small sections around the front left jacking point, the car has been resprayed and currently sits in a single garage full of the parts awaiting re-assembly time scale 18 months on and off doing the job.
In conclusion buy a corsa while repairing the faults because it is not going to be a weeks work and you still need a car.

Regards and thanks for reading this small novel

(yes, i am ready to face the music and rust. am getting very used to it now)
alternately buy two xj40s, drive one while the other being restored and buy the time you're done on one, you can start the other, and the cycle will continue from there onwards.
back to the point though, on my car anyhow, am sure the water is entering at the join of the inner wing area to corner of bulkhead as i had rust around that are at the bonnet latches. i have had the bumper and front fairing off before, so have been 2/3 of the way in to date. so ready to go all the way. my bulkhead is generally very good and am hoping to keep it that way. i found this picture from xj40.com link witch pretty much confirmed what i think mine will look like one i get in there. got to be done soon, now its getting dry again and can start working outside.

The picture is of a pre 92 car as the main cable harness runs through the bulkhead, the area of rot is the sunroof drain tube these were not welded in place and have a mastic goo spread around, on 93 cars the harness exits the panel below the drain rubber tube in the picture as you can see the hole in the picture is where the indicator harness goes through note that the area was masked off so the the sealing cable grommet could seal, the same is done for the harness grommet and that is where the water gets in poor sealing.
