Yes it could be from the window blocks - they have a fibre gasket below them. It could also be the seal under the window frame. The most likely suspect would be the windscreen though. They are prone to leaking, especially with non LR seals.

Common problem. I have a very rusty driver's side hinge/bracket on the windscreen and drops in the footwell after heavy rain as well. Yet to remedy the problem, but think it might be an ineffective seal between windscreen surround and bulkhead. When I replace my windscreen for a new heated one at the end of the year, I will change the seal as well. Additionally I have considered going to a wrap shop and get them to add a strip of transparent stone-chip protector, cut to size, along the length of the rubber strip, invisible to the eye but adding extra waterproofing.

^^^^^ strip of transparent wrap - that's a good idea!
I was just thinking of adding a bead of sikaflex along the length of the foam strip, as I have half a tube going spare right now, but something like that might be a better and neater solution.

hi GeeBee,
it's a two minute job to check the hinge/hinge bolts - i had a leak into the passenger footwell and checked the hinge bolts on that side as the first step - the delinquent bolt was obvious (rusty) and the water track behind the gasket was similarly obvious. the factory gasket is basically rubbish (hopelessly thin) so i replaced it with 3 individual thin rubber washers (easier and cleaner for me than a bead of sealant as recommended in the water ingress manual) and had no problem since. Cheers |

For the windscreen frame to bulkhead seal I dug out the front 1/4” or so of the seal and after masking up filled the resulting gap with sealant, smoothed off it’s no different in appearance to the foam. For the hinge blocks I cleaned them up and refitted with new gaskets and a bead of sealant around each hole. And finally for the windscreen seal itself I jammed the nozzle into the seal and applied sealant right the way around.
Result is no more leaks. Except for those from the roof seams of course... |

I appreciate this is an old thread, but I think my window foam gasket it’s leaking. It certainly looks like it’s tracking around the end as it’s very compressed and then into the cabin. If I Loosen or take the hinge off per the water ingress manual does it all Decompress and then I’ll get issues with trying to pull it down tight again or does it just stay put with the roof compressing it? Just trying to anticipate what will happen and if I can take the hinge right off and seal behind and reseat it or if I should only loosen it.
Thanks! N. |

Should be absolutely fine taking it off. I did mine with a healthy dose of Tiger Seal around the holes to plug everything up.

Thanks all. The water ingress manual is helpful - I was just also double checking if the whole thing just springs apart when I slacken the hinge. I’ll Silkaflex it (only because I have never used tiger seal but I have used sikaflex a lot in the past) and then put it all back together. As well as silicone the windscreen seal. It seems to be the foam seal that’s leaking but it’s hard to tell for sure until I Seal it and then still have a puddle!! I’ll fill as many other bits as I can whilst I have the tube of sika on the go and it’s an excuse to buy a snow cowl too

Ngins - you haven't said how old the vehicle is, or when the window blocks/hinges were last looked at. (If they really are "hinges" then it's pretty old)
But what I wanted to say was to make sure that you have spare bolts to hand. When I last did mine, about 6 months ago, I had to very carefully drill out one of the bolts. With aluminium corrosion (in the thread in the window block) it was completely immovable. I've got a pic somewhere. It's probably a good idea to replace all of these bolts anyway and to put some sort of anti-corrosion barrier between the steel bolt, and the aluminium window block. Second - don't move the car when the blocks are off, because that might allow the body to flex and maybe misalign the holes. Finally, for going around the windscreen seal, have a think about 'Captain Tolley's Creeping Crack Cure'... I had a leaky windscreen seal, and I found this much neater than sikaflex/tigerseal. You just lift the seal a bit, let some flow in, and it's job done. Don't put too much in or it will overflow - be ready with some paper towel to wipe up any of that. But it's good stuff and handy for other LR leaks!

Had these exact problems! Back & forth to Land Rover three times! So, first of all I peeled back the windscreen rubber cleaned out the grit water ect & dried with a hair dryer.
Once cleaned out & bone dry I applied a bead of warm dumdum pushed the rubber to seat it warmed it up again & removed the xs. After that I removed the window blocks & cleaned the area & replaced them with a bead of dumdum around the bolt holes, upon tightening the blocks remove the Xs one once again. Finally run a very thin bead of tiger seal along the foam seal between the bulk head & windscreen surround ( Landrover did this also but made a mess of it) So....even with the weather we have had it’s been bone dry! If the screen has to come out or the blocks need removing for some reason no problem as it’s only dumdum! As for the tiger seal if a main dealer does it I’m ok with it..... |

thanks again to all for the replies - I haven't done the job yet because the weather has been so awful but I'll get there eventually - I'll do a new door seal at the same time and clean it all up. I'll probably sikaflex or tigerseal it but whilst its still wet I was going to push some dumdum into the window seal and see if it stops it temporarily before I do it properly - is 3M Caulk Strip 08568 as near to dumdum as you can get these days?
By the way @donmacn thanks also for the tip on Captain Tolley's used to use it on boats all the time - not sure why I didn't think of it - its good stuff - nice to see you can still get it! I will also heed you advice on the bolts. For info its a 2013 Puma 110 so they are blocks not hinges |
