I suspect not:rolleyes:.
I've got rain water dripping on the passenger front seat but only since I removed the cassette to recover the sun shade then replaced it so the bus was still useable whilst I recovered the headliner.
Between the roof skin and the cassette frame there is a foam seal running all the way round which didn't look brilliant but at the time I thought it was just a bit of cushioning to avoid rattles or some such. :oops:.
The headliner is now ready to go back in but I thought it would be a good idea to find the leak first and fix that incase the cassette has to come out again (and it does, so no headliner going back in today:()
This foam seal isn't touching the roof and it's not really a water tight seal anyway or even meant to be, its a water deflector really but also has some draught proof and water stopping abilities.
Any water that gets past the GLASS seal ends up in a trough which has the 4 drain tubes in it. This foam seal(looks like the stuff you fit around draughty windows that comes on a roll) fits just out board the return lip on the roof body lip and is clued to the flat surface of the cassette. Any water getting past the glass seal drips down the roof body lip,down the face of the foam seal and into the trough and down the drains.
My foam seal is not even reaching the body roof lip so there is a gap for water to get into the cab before it reaches the trough.
My initial thoughts are to remove the cassette and purchase suitable foam strip, it's quite rigid closed cell stuff ,and refit.
Howevero_O ,the roof skin bulges outwards in the front 2 corners (where the gap is) so I suspect the foam seal is shaped, being taller in this area so a bit more faffo_O.
I can't find this foam seal by googling and I suspect its not available as a part anyway but if anyone knows different speak up:).
Other than that the whole cassette is in excellent condition.
Couple of pics with a pen pointing at the foam seal.first pic ,to the left of the pen is where the foam seal has shrunk and isnt touching the roof skin.2nd pic shows where the foam seal and the roof skin lip that its suppossed to be outbound of.

A new foam seal would be ideal if not too pricey but I could build up a new one in layers to adjust the height where the foam gets taller but what a faff and time consuming and it might rain too.

Can you not put the thicker foam stuff in and it'll just squash down where required?

You can buy foam sealing strip with on side adhesive.

There's quite a difference in height and I suspect the seal will 'tip' before it squashs enough, it's fairly stiff stuff which is why I think it's shaped originally.
For speed and convenience a new genuine seal would be preferable as its bloody heavy to keep removing/refitting. Bolts are a bugger to get in as well as holding it up. The Doris put her shoulder out helping me. I can sort it one way or another if no off the shelf seal is available :cool:.
 
Found a pic on ebay that shows the foam seal running all the way round. It's the lighter grey ridge on the outer edge.

Put the sunroof in place draw around where it goes, stick a foam strip to the roof, instead of the sunroof? Maybe double up in places? The double sided stuff might work well?

Feckin bodger!:D.
Just ordered some epdm foam tape orf ebay, 5 mtrs 20mm wide 8mm thick, I'll lay it on its side and glue it on its edge to the cassette frame. I've measured the gap where the old seal fits and it's 15mm all the way round except the front where it's around 22mm. Hoping it will compress nicely and maybe add a bit more thinner stuff around the front:cool:. Got a roll of 2mm stuff somewhere:).
£12 delivered.

Fingers crossed the stuff I've ordered will squash 25% without stressing the glued edge.
Gripping stuff this.:p.
Thinking of fitting some m6 studding into the sunroof captive nuts to enable controlled/even pulling up of the cassette.
Bloody heavy awkward thing it is.
Work smart not hard:cool::D

Pleased neither of my runners have a sun roof:cool:
 
@Dopey all ready got the foam, see above, glued it on today using contact adhesive.
Hopefully reinstalling it tomorrow if I can get help, otherwise it'll be the day after for sure.
 
Well, it's all squished up nicely, the studding was a godsend for pulling it up. I'll leave refitting the headliner until I'm sure it's leak free.
