Update
All the rear is now stripped out. All panels are in excellent condition considering the water and the age
I have also found the missing airvents!!!!!! They are hidden behind the O/S rear lower quarter panel, there are two vents with little valve type flaps to stop air/water coming back in presumably. I can't see how the air is supposed to get to them though as its all cased in by the panel?
Still, at least they do exist
Since driving to/from work with the rear windows cracked a little, the condensation is much better so im guessing that the whole headlining saga was caused by a massive build up of water inside condensing onto the roof and flooding down when driven.
I'm hoping to get her indoors on sunday to mastic anything that does not move
So do the vent to undar the wheelarch?

Just ordered 4 of these. That will hopefully keep me going for a little while.

That's about the only place I think, they vent into the double skin void but I'm not sure where there is another opening for an outlet.
Still, at least they are there

The vents sound pretty useless in the location they are in. Ideally there should be one on each side of the vehicle to provide a cross flow of air. Dry fresh air comes in , and damp stale air goes out. One vent on its own isn,t much good. Thats the general rule in buildings.That's about the only place I think, they vent into the double skin void but I'm not sure where there is another opening for an outlet.

This made me think as I used to be a coachbuilder and i have fitted hundreds of roof vents and I can still get them at trade prices
I think a vent is a definite answer as they are widely fitted on vans, coaches etc to help prevent condensation.
This low profile one is the same as the one above but with more info, these spin when the vehicle is in motion or even the wind can rotate it when its stationary, but its still sits quite high on the roof and may get knocked.
This type however sits lower and still works well and can be painted (Im pretty sure they can be) and looks much neater, but needs the vehicle to be in motion to work. I have just climbed on the back of my Disco and measured behind the rear sunroof and this type of vent may well fit ok.
I will order the one above on Monday as my Disco needs it and let you all know how it looks.
Basically you cut a hole in the roof, bond the top part that spins to the roof (most vents of this type normally bolt or screw on. I have never fitted a bonded one).
Then the grill part fits on the underside of your headlining, you would need to make up a packer to put between the headlining and the roof panel thats pretty certain. I normally use a pieces of plywood with the same diameter hole cut in it.
I have had a dehumidifier running in the car all week and removed a good amount of water so the interior is now dry, Today I have also removed the sunroof pannelsand cleaned the rubber seals, washed them and resealed them in and refitter the glass. They are now tightly shut till the sealant sets.
I did notice before that I could see light in places between the glass and rubber seals. Now there is no light visable. Fingers crossed.

The interior is now dry. I siliconed around and under the black outer frame of the sun rooves and siliconed the rubber glass seals in place. All is dry even after the wet weather we have had over the las couple of weeks. The carpet is also dry and will be refitted when a suitable dry day is available. Maybe Ice in the cold weather damaged the seals.
