Leak or condensation?

(1/3) > >>

stefan:
Me again! I replaced the door seals on the 90 the other day, which should hopefully stop some water ingress (except from the rusted door bottoms), the doors certainly need a bit more of a shove to close than they used too! However, I've always had water dripping on to the top of the door, which appears to be coming from up inside the headlining, I've run a bead of silicone around the frame of the sunroof outside, and smeared the rubber seal with vaseline after giving it a good clean. I reckon the water is condensation, sometimes there is loads which comes cascading down if I come out of the drive at a slight angle. Who else has this problem (I know it's not just me!!), I've heard somewhere about removing the headlining and placing insulation between it and the roof, or could it be water leaking in from elsewhere? Any thoughts?

Hi Stef

I don't suppose you've got air vents above your rear door have you?

I'm assuming you've got a full length headlining if you're a CSW. The water can enter through the rear vents, and then run along the inside of the headlining (where the roof meets the sides) and then drip out at the front of the vehicle. Especially if you park slightly downhill...

Thankfully I don't have too many leaks on my 90 at the moment. Long may it continue!!!

Cheers

Ben

hehehe

All the time :-)

I get condensation coming down by the sides of the lining.

On my Series 3 I cured it by gluing polystyrene to the roof and lining the whole thing.  When everything dries out, I will so something similar to the 90 and then put the headlining back in over the top. (Might even invest in a posh LaSalle jobbie)

Ben,

Being a 'proper' CSW it does have the rear vents and full headlining. If I seal up the vents, is it best from the outside or inside and has anyone done this? What did you use? I suppose I could just seal them with silicone sealer?

Stef

P.S My drive looks bare without the 90, can't wait to get it back!!!!!

I have a similar problem with my 90, water comes only came in when it was raining and on the move, it never came in while the vehicle was stationary. (Strange!) I have put a small deeding of silicone around the outside of the seal of the sunroof, which has stopped the rain coming in, but still have a condensation problem. It’s a common thing with Defenders; everyone I know has the same thing. I was thinking of installing air vents above the rear door as it has been suggested that this might cure the condensation problem. But reading your comments it might start the rain coming in again.
