Sunroof Seal Issue

I tried posting this on thectail of an older sunroof thread but it doesnít seem to have been noticed.

I am in the process of installing new seals on my SC. Before removing the old ones, on both the roof and the body, I marked the location of the ends.

When I installed the sunroof with new seals yesterday it would not close all the way. The issue is that the seals interfere with each other too much at the rear, preventing the back of the roof from going up into position. This is operating the roof by hand from under it. That being the case there is obviously no way the hand crank or motor could ever pop it into place.

Anyone else run into this issue? Iím thinking trim some seal off of the sunroof on either side, but if I do it will not be coming ďaround the cornerĒ of the roof as far as the ones in the Images here, nor as far as I marked my roof before I took the old seal off.

Did you remove the cables and check them for dirt build up? If the roof wont close the cables are the usual suspects. I would remove the rails and clean everything up. The position of the seals shouldn't impede the roof closing.

Cables were R&R and are clean. Also in this case the cables arenít hooked up, just the fron guides. I was trying to close the roof manually, from the inside, and the rear of it will not pop up to complete the closure. Too much seal interference.

And I did refer to the link mentioned above, quite a few times. But the issue I am having isnít covered. I think Iíve done everything right, it just is not working out. Must have overlooked something.

You have to hook up the cable guides they're what raises the roof on the back. The metal springs also have to be in place. I'd hook up everything and operate the motor. The cable guides over cam when pushed by the motor and raise the rear of the roof in the closed position.

Same issue with mine until I messed with it a bit. Make sure the screws are not too tight on the things that pop the roof up. Mine were too tight and it wouldnít push the roof up after replacing the seals. Backed them off just a hair each and it worked perfect.

The part of the seal affixed to the roof has to be slit open, and the inner tube cut away, for an inch or so at each end. The procedure is clearly outlined in the shop manual. The process in the thread linked above will work, but it's wrong.

Steam Driver, I found a few pics of my setup that works for me.
This is a An original Porsche seal. Some after market ones are longer and may interfere with the sunroof getting home at the back.



The rear is pushed up and ďlockedĒ into place by the level linkage.



The lever system is quite powerful. I do not think that pushing up by hand will give you the same result. Also, the lever is adjustable for height which can only be done by removing it from the sunroof.
You may also wish to revisit the placement of the seal at the rear top of the sunroof. A fold or improper placement may prevent the sunroof from getting home.
Hope this helps.
Johan

Thanks for all the help, particularly Tom F2. That item about the splitting is not covered in the Bentley manual unless it is someplace other than in the Sunroof section. I donít have the regular manual.

I will PM you on this.
