Windshield Seal Install Question

[76FJ55]

Based on the description on their site Sierra Madre is supplying genuine Porsche windshields, so I'm inclined to think it is extremely poor installation and not the glass that is the problem.

[arbita1]

So the shop is telling me that the frame is bent and that was the problem. I haven’t seen any damage at all so I’m not sure what they are talking about. I have this photo from when the glass was out and do not see anything.



He also recommended to use sealant which I’m not crazy about. After some back and forth he offered to take another look at it. I’m hoping I can just get the seal to lip over myself so I don’t have to bring it back.

I had to roll the 74 outside to do the brakes on my nephews truck, it rained and since I had the carpet out I noticed a small puddle. I found some rust perforation through the frunk weatherstrip gutter along the top and am about to order a cowel panel from restoration design and a windshield weatherstrip. None of the reviews of the weatherstrip look very promising.

Any suggestions? Do I need to order the trim as well, or is it re-useable.

Thanks,
chris

Owner keeps asking me to look the car over and make sure it's satisfactory. I told him "You're the professional. I shouldn't be able to find anything that you haven't already addressed and if I do, I just won't bring the car back to you for the next detail"

People just don't seem to have the attention to detail that they should have. It's just "get it in and get it out" and that really burns me.

The new URO brand "wide" windshield seal will adress these issues. Do a search
I was a stickler for using only Porsche seals but this new product from URO has really won me over
I have been a Porsche tech for 40 years and installed hundreds of these for context

I was able to get some of it to seat correctly. But there is a 10” section that is being difficult. I had my 13 year old son try to push down on the trim while I tried to get the inner lip to grab the frame but no luck. I’m afraid to put to much pressure on it and crack the windshield.

You can see below compared to the picture above that it is getting better.

Try gently pushing on the windshield itself rather than the trim, while hooking the seal over. Not too much pressure but enough to maintain compression on the seal. Pushin on the trim won't help because the windshield itself has to move into position itself and take the gasket lip with it.

I agree it's the windshield that is too far out, not the trim.

Post pics of the seal down by the wiper arms. It is likely too far out also, and the effort you are spending on the top may be in vain.

911 windshield seem to be tricky for a lot of glass installers, so you may need to check with your local air cooled shop to see if they have a recommendation for an installer.

I just got car back from the paint shop, and though he's good at spraying, he had another shop send a tech over to do the windshield install. After ripping the seal, he conceded and told me to take it back to the last shop I had the windshield installed at, and have them send him the bill.

Now that's integrity!

I'm not complaining. The project of course has taken a bit longer than originally estimated, but he's been really good at addressing all the issues that have cropped up so far. I even know the shop and tech that tried to do the instal, and they've got a great reputation for both air and water cooler cars, but this windshield beat them into submission.

Here is a pic at the bottom. I think it looks ok.

I just did a windshield that was a total PIA - OEM seal and glass. Sometimes its just difficult. I was having the same issues as you, I had 2 buddies come over and they pushed the glass in while I pulled the string. We even had to slap the glass up so it sat in the top channel correctly. did you try that? Your glass may be slightly low and the gasket is not catching the lip on top.

After reading what you posted as their response, forget that shop... they're clueless. Have a friend push down on gently the seal from the outside, get a plastic trim removal tool and slide the seal over that metal lip on the windshield frame. Then you might need to take a block of wood and tap upward on the seal. There are instructions for "forming" the seal around the windshield frame all over this site. The "frame" they are referring to is likely the metal frame that goes inside the seal that helps form and hold the seal around the windshield. If you pulled the old seal and weren't careful you could have slightly deformed the metal piece. It's not the end of the world and can be formed once in place as long as it's not REALLY messed up. In fact it's common if you look around this site to have to do a bit of tapping on the seal to get it in place. The corners are normally the hard spots. I had to tap my corners when I installed my own windshield. Mind you, I am not a professional windshield installer.

Did you show them the pic or explain to them that the seal is not seated properly inside the car? It's being held down because the seal is not installed correctly. The seal didn't pull into place at the center point at the top of the windshield. The top center is likely where they finished pulling the rope out of the seal during installation.

I kind of feel that the seal may be too low and needs to move up. Where do you tap the windshield to get it to move up.

I had them provide new trim because I felt my old ones were too bent to reuse. The corners were an issue too. But I took care of that yesterday by tapping them into place. I was thinking of tapping the top trim up a bit as you recommend to see if it would help but was afraid I may dislodge it from the seal.

All over really, just make sure your hitting it up. It helps a bit if the seal is warm, maybe try it out in the sun. If all else fails, have them pull it out and start over and maybe lube up the channel where the windshield sits a bit.

Same problem here
My car is a 930 1989 late production
Was told I have a 964 window frame on late ( March 89)
Production . Is this true ?
Would the uro seal fix the problem ?
Thanks

You have to get that lip on the inside straightened out first. I got in my cab and looked at my seal. I think one of those plastic trim removal tools would go right in there. The lip in your first pic looks like it is folded under which is preventing the seal from sliding into place properly. You shouldn't be able to see much if any of the metal lip that the window seal is supposed to slide onto.

A set like this is a handy thing to have around as long as you don't have a kid that helps his friends install stereo systems in their cars and leave the tools in their cars... never to return.

BTW, 4th tool from the top in that pic is the one I'd envision using for what you need to do.

You do have a 964 windshield frame use a Porsche 964 seal
Cars with these windows do not have metal trim in the seal
if yours does someone has installed the wrong seal

I have a new Porsche 964 seal and the corners don’t fit great. I have tried all
The windshield is a Pinkerton 964
URO does not make oversize seal for 964
