Exchanging the roof rubbers on a 993 targa
Hi,
Allthough they still look quite good, the rubbers on my '96 targa have never been exchanged and I am experiencing some wind-noise. I am wondering whether it is going to be worth the effort to exchange all rubbers in the roof system.
Anybody has a idea if this can be done as DIY, and what the costs/benefit equation is like?
Thx, Bart

The bit of rubber on the front piece of the glass, which acts as the surface for the compression seal against which the deflector presses down on, can apparently just be pulled off and a new one pushed on - my local specialist did this for me and adjusted the way the glass roof panel sat and this completely eliminated the slight wind noise on my MY97 Targa.
The other seals on the sides and back of the glass panel require the entire roof to be removed and this is very labor intensive.

Bart,
Tell me exactly which rubber seals you are planning on replacing? (part #'s or pics would help). Because it's not always a seal which causes wind noise.
Refer to the TSB from Porsche called "Noises from the Targa Roof Area". You can find a copy on Mike J's site at:
http://www.pcarworkshop.com/images/a...1997_66037.pdf
There other adjustments that can be made such as the thread insert bolts which close the wind deflector (see section 1.1 and 1.2) and the wind deflector side mounts (see section 1.4). There can also be slack in the targa glass guide cables which can occur over time due to cable stretch. There's a little trick to tighten this up. (see section 1.3)
You may have worn rubber seals, but often times there are other adjustments which tighten up the top to minimize these noises. More often creaking noises occur when seals go bad. Just my experience.
See if you can send a photo of your wind deflector fully closed from the inside AND outside the car. That would give us some more information. You can also run your finger along the front frame of the sliding glass top from the inside and see that it is even and very close to glass of the wind deflector. I wish I had pictures to better explain this.
Good luck

Bart,
I find the most revealing pictures are when the wind deflector is closed, from both outside and inside. The deflector rear edge should lay pretty much flush with the glass top when the top is fully closed. (See my pic).
From what I see in your first picture I believe your wind deflector can close a little bit tighter.
See my first video at:
http://www.youtube.com/my_videos_edi...next=my_videos
Also, when looking from inside the car, the wind deflector right and left mounting brackets should lay parallel to the guide rail on either side with little space in between (may 1/8").
See my second video at:

If it appear that your wind deflector is not as tight as mine, then consider the TSB I referred to in the previous post also found here and read section 1.3 "Eliminate the play of the wind deflector drive cables" as a way of tightening the wind deflector a bit more. If it then lays flat but still has wind noise (< 60 mph), then consider replacing the gasket on the front of the glass top sunroof (part 993-562-531-00). It is relatively inexpensive and can be pulled out and replaced very easily (mine isn't even secured with any adhesive).
Hope this helps -

Hi Marc, Big thumbs up for your response... Very clear and helpfull. After checking I think you are right. The deflector can be tweaked a bit to get it more flat. Will check out the options to correct.

I doubt it.
You can also adjust the wind deflector fore and aft by using spacers on the hinges. Normally not needed, but if someone has changed the seals, often the roof alignment changes.
Someone also said "The other seals on the sides and back of the glass panel require the entire roof to be removed and this is very labor intensive." - this is not true. The large glass panel can be removed without the roof being removed (its not easy though), and the window and trim seals can as well.
However, I would recommend to fool with the seals as little as possible. They are expensive and tricky to install.
Cheers,
Mike

Bart,
Sorry, I was on vaca in Maui. Forgot to check the thread.
Actually, yes I did remove the retractable sunscreen. But that's because I did a lot of work on my top (long story). But Mike is absolutely correct. You do NOT need to remove the sunscreen to work on or even remove the glass panel.
The glass panel, although it helps to know how it fits, can be removed by one person fairly easily. The key is removing the entire cover strips on both sides before you remove the glass. Then the glass panel just lifts out once you unbolt the front and rear axel plates. I would recommend you cover the bodywork with towels so as to not scratch anything.
Hope that helps!
