SC windshield replacement

rpiper · 06-12-2003, 10:28 AM

My SC needs a windshield- nice crack where a rock hit. I remember reading in here about some holes that are exposed when the windshield is out that can be plugged to reduce the wind noise (I have awful wind noise now despite all efforts to eradicate it). Does this sound familiar to anyone? It's not in the archives that I can find, and the glass company's coming out tomorrow to replace the windshield. I figured while it was out I'd plug those holes. I need to know size etc........ Thanks

I performed a glass replacement on a '78 930 a year or two ago, there are no holes that I can recall. If the gasket is properly sealed to the windshield channel, there should not be any wind noise issues here.

I believe there are some plugs that may be installed in the doors that reduce wind noise.

Make sure the holes aren't designed to allow water drainage.
I believe KTL (Kevin) recently restored his Carrera windshiled frame. Perhaps you can shoot him a PM.

The only holes I know about are underneath the door. There is a service bulletin about this.

When your windshield is out, be right there with a wire brush on a drill and clean up any rust you see at the bottom corners of the body-to-windshield flange. Treat them with a rust killer. Buy the windshield guys lunch so they give you time to do this.

A new seal may be in order? Also, do you intend to retain the trim? If so, the seal will need to be the type that accepts trim (i.e. is not "trimless").

Best of luck,

check with your insurance company about the damaged windshield - you may be eligable to claim it under your comprehensive. I did so on my SUV and had a $50 deductable. sweet.

There are no holes for windshield drainage. There are some hole in the leading edge of the doors that should have some plugs in them. Look with the door open. If your hood doesn't sit tight to the smile you might get some wind noise there also.

When my car was in the shop getting painted, I had all of the glass removed. It's not uncommon to find rust in the window channel especially if the windshield was replaced sometime in the past. The glass guys stuff a knife or razor into the rubber and more times than anything they cut too deep,exposing the metal. Rust forms and in no time you have a rust problem until the glass comes out. My windshield was replaced sometime and suffer from a tiny bit of early rust. Once stopped the entire car was painted. I had the shop call my insurance company where I learned that they approved a replacement windshield, but get this, they even approved German glass which I heard was $850.00 but all I needed to pay was $50. BTW, wind noise enters from holes in the door panels if not properly plugged.

The glass guy just got done. He showed me the old windshield, which he politely said was the sh--iest one you could buy (po had it installed). Bottom line? It was too small, thus the seal would not rest outside the window frame, causing the wind noise. I have already plugged all door holes and replaced all seals, and replaced the metallic tape between the "wing" windows and the outer door skin under the chrome trim. I think the only thing left is to replace the stick on seal on the door frame, which has hardened to rock. Is this a Porsche part # or should I use some 3M product...?
