Leak through windscreen?

If I have water dripping in right here from above the windscreen, where exactly has failed? On the outside or inside do you think?

Pull the ceiling panel out and check, as water does "travel" as it leaks into the Disco roof.

May be sunroof, roof bars, corner of windscreen / gutter, alpine lights or it could be the windscreen.

Thank you

I've got the whole headlining out due to a leaky rear sunroof so might be travelling from that??

Had it out 3 weeks and just deciding between trying to repair it or just seal it shut somehow!!

If it is the windscreen, is that not strange as the whole thing is bonded?

Well if you have the headlinging out you should be able to see where it is coming from, photo looked like it still had the headlining in place.

Have you read the landrover disco water ingress manual, including the addendums for the gutter areas?

Can you link it for me please?

Also, do the drain tubes just pull off of the drain cups? I tried but just feels like it is going to snap it

If you have the headlining off then you might as well re-seal the sunroof frames to the roof, as the headlining is the worst part. I used glazing type flat sealing strips on the front sunroof and sealant from a tube on the rear. I also sealed around the cups. I also bought two rubber seals which I haven't used. Both sunroofs have been dry since. I found the flat strip was less messy, but both have worked.

On my Anniversary the windscreen leaked at the top, a replacement had possibly been badly fitted, resealed it with proper winscreen fitting type black silicon, never leaked since.

Whereabouts do you physically seal though?

550 miles away and about 10 years away from doing this, but I seem to remember peeling the top of the windscreen surrounding rubber back and then doing it. But others tell me I can't have done as it is bonded in.
I definitely did it and it has worked, so I suggest you look for what might work for you.

Yeah the previous guy (seems like an einstein so far eh!) Has put so much silicone over the outer seal that I dokt know where the seal and the sealant merge!

As its bonded I should be able to just take all of that off with no risk eh?

Then apply sealant and get a new windscreen outer trim/seal?

Others who have done it will jump on. I haven't done it on a D2 which has a bonded in screen so I dare say no more.
Get told off again if I do, which happens here on a regular basis. (Gives others a laugh!)

As for previous owner being Einstein, I think when a vehicle gets old and not worth much money it tends to attract two things, one is the attitude, "its not worth spending too much money on this let's just bodge it." and the second is the impoverished owner who cannot afford to do a job properly so just bodges it.
Don't know if I quite fit into either of these two camps yet, have yet to do a serious bodge although some on here would disagree!

Many bonded Disco 1 screens that are not original fit or have been badly fitted leak and over time the windscreen frame rots out in the corners, so no matter how well they're fitted the water leaks in through rust holes into the cabin. The stupid design rubber surround bit that is super expensive and a real PITA to fit whilst putting in the new screen contributes to making a bad job of the seal. That rubber gets water behind it and the road dirt and dust that gets in with the water makes mud and keeps the frame wet speeding up the rot.
If you ever need a new screen fitted get the fitter to leave off the rubber trim, throw it in a bin and just get the windscreen frame surround done in black silicone, much better and will be waterproof, plus the main bonding will be 100percent better due to the absence of the clips that go between the screen Glass and the frame flange to fasten the rubber.

Aha! so I WAS right when I said ages ago on another thread that I had used silicone sealant to seal around the rubber around my D1 windscreen!!
I knew I'd done it, and it worked, but I didn't know my screen was bonded in and the bit I sealed was not the windscreen sealing rubber but another rubber around it!!
Thanks for explaining this and if it starts to leak again I'll know what to do!

1989 to 1994 200Tdi era were rubber sealed and the 1994 to 1998 300Tdi era were bonded screen with that terrible glazing mastic stuff, typically the sceen is more curved than the aperture and they don't put enough sealer in there to seal the screen or they scratch the paint off and the steel rusts and slowly the water leaks in.

Rust! Does it, u say “ they don’t put enough sealer in there to seal the screen” I assume that an after market fitter as I can confirm the factory did, never had any issues with water ingress win my disco, I wonder why, maybe because I have looked after it

From factory they were mint around the screens, just the rest of it rusts away before your eyes.

My reference was to the fitting of aftermarket screens, a well known problem being that the new glass is more convex and the gap is bigger.

If the "new screen" is more convex then it ain't the right screen for the job is it? Mind you, we are all used to body panels that only fit where they touch. Mind you again, you can't belt them with a hammer, weld them into place, cut and replace bits etc. What a mess! Typical idiots making rubbish then still taking your money for it.

Can also be that they are made to a mould and given that Land Rover build tolerances are very "interesting" then it's possible that they fitted the mould given and as so few seem to leak then perhaps it is the build tolerance?

Who knows, but still needs more mastic.
