Alpine seals

Had my local indy replace the alpine seals on my 110 as mine were looking past their best.
They are supposed to have been genuine LR ones but the seal is ruckered up at the ends on the inside and they leak like anything.
After the rain today the rear
seats, carpet, and inside of the doors are soaking wet.
The old ones looked bad didn't leak at all.

How can l tell if they are genuine LR parts?

l've had to put insulation tape round them
to stop the water coming in.

No idea how you would tell once fitted. By now LR ones are probably just aftermarket ones put in an LR packet.
When I did my rebuild I'm pretty sure I just used Britpart ones. The filler strip I definitely had to trim to the correct length once I'd worked it around the seal and got near the starting point. Can't remember if I had to trim the main part of the seal to length. Yours looks as though it may be under too much pressure because it is a tad too long? Or, it hasn't been seated over the roof edge properly.

From what I can remember about fitting mine, there are 2 different seals, one for 4mm glass and one for 5mm glass. I don’t know if they have used the wrong seal for your glass, but it’s one possibility. The other thing that’s possible is they have fitted the seal “back to front” in that the glass is in the roof channel and the roof in the glass channel. Personally, I don’t think fitting them is a hard job, so would advise you to remove them and refit them properly. I used britpart, and the seals leaked a little, but I used glazing sealant around them and they are fine.

I couldn’t get original ones for my Discovery 1 so had to use Britpart, likewise not as nice a fit as the original ones,
I left them a week then run a bead of 3M Windowscreen sealer around both outer and inner edges to make sure they are watertight,
I am also going to use some silicone grease on the rubber outside to stop them drying out and cracking overtime,

Well l took it back and they apologised and did the job again, these seals they fitted today look a lot better, they fit better, and a hose test revealed that they don't leak.
