Ok so following on from my other thread here
http://www.landyzone.co.uk/lz/f8/water-leaks-131663.html

I have the inside stripped out at the back and the headlining down waiting for the weekend when i can get her in at work to seal it all up.

This morning, the rear is flooded again, but it seems to be from condensation, the roof is dripping inside but dry outside?

I have a feeling that this could have been what caused the headlining to be soaked before as the one or two drips from sunroofs etc would not make this mess, i know the gutter leaks bad but the headlining was clear of that.

is this normal? or should there be a coating or something of the inside of the roof?

If it gets this wet behind the headlining, its a waste of time putting it back i think.

any ideas
 
if you dont put headlining back how would you stop the condensation, i have had landies and transits with no lining and they drip on ya when driving and have had ice on the inside no good for me tools either ;)
 
Hello dave, Yes condensation can be really bad and cause all sorts of problems. Ive been in building trade for years and seen what it can do in buildings. If there is a lot of moisture in the car [wet coats left in the back or wet dogs and blankets etc] can give a more humid air and it will condense on coldest surface once the car cools overnight. Try fixing a piece of tin foil over the roof window,leave it overnight check it to see if water droplets are forming on it .Condensation will always be worse on very cold nights.
 
Yes, the wet-coat point made me think. There must be water inside still for it to condense as mentioned, it can only mean the middle or front mats are wet too.

Can these be removed easily, i know the mid-row seats have to come out as the bolts go through the mat, but is the front/middle all one piece or split and can the front be easily stripped ??

I dont think i'll win this battle unless i can get all the inside dry after its sealed, cant be doing the electrics any good either.

Ive noticed on most cars and vans there are air vents that give continous air flow to the vehicle . I cant seem to find where they are on a disco. Maybe why its so bad with them ?

Vents at bottom of windscreen, only ones I know of anyway.
 
Thats a good point, most cars have a vent in the rear pillar or inside the tail-gate section to let the air out. As said, i cant find any outlet on the disco!

Anyone knw whats involved in removing the front carpets???

Air vents would just let water in when wading though.

Nah, they are usually high up:rolleyes:

On most modern cars they are hidden in the gap where the boot or hatch opens at the rear, older series and defenders had them above the rear quarterlights, the disco has none:confused::confused::confused::confused:

I guess they just rust from the inside out??

Might also explain the lame blower output as its just blowing into a sealed metal box?

After trawling t'net it seems that to remover the front carpet and soundmat, all the seats and centre console have to come out, does that sound right???

I want to refit them of course so cutting them up is not an option.

Seems a big job just for the mats?

Dave
 
What I did on my last one is remove the front seats. Then I could lift up the carpet and get to the sponge underneath.

I then used a stanley knife to cut out the sponge as much as I could and left them out in my garage to dry, with the help of lots of old newspaper.

After they were dry I could put them back in and you would not know they are cut under the carpet.

If they need drying again its easier next time.
 
I've removed the carpets and foam from my Disco perminately and currently the roof lining is out whilst i have been trying to seal up any leaks.
But everytime its left outside the roof gets covered in condensation. Dunno how the moisture is getting in but looks like theres nothing i can do about it.

Dehumidifier ?
 
the natural moisture from the air will condense on a cold surface(cold unclad roof)-putting the lining back to insulate will stop this once you are confident there is nothing "extra" coming in
 
I was just thinking the same thing. Mine suffers from condensation. The widows mist up at night. Where would be the best place to put vents in the roof?
Is there some insulation material that could be fitted to the underside of the roof skin?

If the fan isn't blowing bery well because it is blowing into a sealed box then if you open a window a little the fan should blow better.
 
I drove home tonight with the back door windows open an inch to get some air in, had the heater on high too, it didn't feel so damp by the time I got home. I'll check for steamy windows in the morning.

I might just lift the door strips and slide my hand under the front mats to check for damp, might be ok and could save stripping out further.

I really can't believe they built a motor with no air flow through the cabin, it just don't make sense at all. I'm gonna have a closer look in the rear quaters, it's the only place they could be hiding.

Stroll on Sunday, I can't wait to get the old girl dry and comfy again.

Should I rake out the mastic in the gutters or seal over the top of it??
