windscreen noises

[Tiptronic2]

I recently had my windscreen refitted due to an issue with leaks around the screen on the passenger side of the car. Ever since I have been getting rubbing noises coming from the screen. I had the work done through and OPC and they have suggested that it needs teflon tape applied around the screen seals. Has anyone here done this and is it an easy DIY job.

Thanks

I had the same problem with a new screen fitted, however I used Teflon Bicycle oil under and around of the 'outside' rubber and that works you just have to do it about once a year. Also check in the bottom corners of the windscreen rubber and lift slightly, that's where water collects and rusts.

Shame the OPC didn't do it properly for you. Unbelievable they suggested it as an afterthought - it is I understand an official Porsche remedy.

I think the main problem is OPCs out-source the work to glass replacement firms whose fitters are not aware of the teflon tape. I've also talked to a couple of Approved bodyshops about the issue and was faced with blank expressions.

I will have to do some retrospective work on mine though because it is now chirping like a canary. I remember reading here a while back that a bicycle lubricant/grease is the best thing but I'm damned if I can remember its name. I can sense an evening looking through old posts coming on []. If anyone can save me the trouble I'd be grateful, also does it go under the outside rubber where it sits on the edge of the window opening or does it go in the aperture between the glass and the body?

Quite apart from the teflon tape (which i agree should be done on all 993 screen replacements as a matter of course) i'd also suggest trying a strut brace.

I bought a brace from JZ for a couple of hundred quid many, many years ago and i kept it from one 993 to the next. In total it did 100,000 miles in my 4 993s and in each case i fitted it within weeks of getting the car and in each case i could feel the difference. Less so on a C2 with 17s and stock suspension, much more so on the turbo, but noticeable nonetheless.
For something which takes 10 minutes to fit (you have to put a slit in your carpet) and costs so little it makes a substantial difference to turn-in and to squeaks and creaks.

I had no problem until I had a new windscreen fitted. I've tried Ice Wax, which was recommended on here, but that dosn't work for me. (It does put a lovely shine on the paintwork though, so money not entirely wasted.).

Where do you get this Teflon Bicycle Oil ? It sounds like it's worth a try.

Strut Brace sounds like a good idea, but it's £200, and presumably gives awkward boot access ? (I carry logs and coal and manure in my boot sometimes).

 

[verysideways]

You can get them cheaper, down to about £120 i think, and doesn't really affect access as they run across the top above the fuel tank.
Pop your lid, peel back the carpet directly above the front wheel hubs, you'll see the strut tops.

Here's an example borrowed from the interweb:

 

[Porker993]

Teflon Bicycle Grease sourced and fitted. No more squeaks this morning, but then it was raining which suppresses the noise. It seems like excellent stuff, so I'll see how long it lasts.

Teflon oil/grease sounds a good idea (as does a strut brace). But won't any 'oil' component attack the rubber seal??

 

[Porker993]

No, the seal seems pretty indestructible. A new seal only costs about £20 (?) so well worth it in my view.

Day 13 and still no squeak !!!!!!

I think we've cracked it Jim !!!! (With the aid of a little Teflon bicycle grease)

So where did you aquire the teflon grease/oil?

I also used the teflon oil ,stopped it completely.You can get it from the cycle department in Halfords,
It has been ok fo 18 months now
It comes in a squeezy bottle and is used on cycle chain

Mark/Fred, I bought the teflon bike oil last year but never got around to applying it. Wanted to test on a hidden bit of paintwork first just in case.

Where do you apply it? Is it to the top, bottom and sides of the windscreen and is it to the inner edge of the rubber (i.e. between screen and rubber) or to the outer edge of the rubber (i.e. between rubber and paintwork)?

Thanks,

David.

 

[MrHappy]

Applied it last night, by lifting the outer edge of the seal, between the seal and paintwork. What a revelation, squeak/creak has completely gone!!! [] [] []

Before applying I found that, using finger pressure around the outside of the screen, I could make it creak in a couple of places. Made it easy to locate and treat the right area.

Sorry I didn't reply to the posts above. JB, yes, I got mine in Halfords bicycle section. David - sounds like you've found the right application method.

PS. Mine is still sounding pretty good on day 30. Best of luck all.
