The replacement seals turned up yesterday and I fitted them to my car this evening.

The reason the seals grab and jam is that you/we have the WRONG seals. It’s obvious when you hold them side by side.

The seal on the left is the 914 seal, the right is a 911 seal.

Image

As you can see the left hand one is shallower & shorter and has an extra part that reaches down by the “bulb” locating strip to stop it “rolling” into the glass.

I fitted the correct left hand seal tonight and the windows wind up and down with ease, just as Porsche intended.
The answer isn’t talcum powder, its fitting the correct seal.
The confusion is that 914rubber and other vendors sell the 911 seal and list it as a 914 seal.

Hope this helps.

Regards
Darren

No, this is not correct Darren.

The seal on the left is not a 914 part.

The 914 door to window scraper that the factory fitted does have a lip on it.

Darren, can you post a photo of the packaging of your GENUINE Porsche part please?

Did you buy from your local Porsche Centre or through a parts supplier?

Darren, why would a manufacture use a different off the roll bit of rubber between their cars?
Wouldn’t they use the same basic rubber and just cut the length and ends to suit the individual models i.e. 911 and 914?

I have dug out my new Original Porsche supplied rubber window scrappers that I bought over the years from Porsche Centre Guildford.
They all have the lip which rest against the glass and on the reverse side has two fine raised lines
that make contact with the glass.

The one in the box is the left side and is years old; marked up as being stocked by Porsche in 19.09.88 and the other two are the right side I bought at different times around 8-10 years ago.

I have checked with my local Porsche Centre for available stock and the left side is still available and the right is no longer available.
As I haven’t quite got a matching pair I have ordered the left seal and will let you know if it differs from the others supplied years ago.

Thanks Kev,

My replacement seals came from Stoddard via 914rubber, unfortunately I threw the bag out last week when they were fitted.
I was told that the "early" cars had this seal which was superseded by the 911 seal by Porsche during 914 production.
How true this is I do not know, but may suggest why you have 911 "type" seals dating back to 88.

The seal does have the very thin lines moulded on it where it wipes the glass.
Also of note is that it is exactly the same width as the rubber on the base of the quarterlight seal, so the seals look the same on the quarterlight as the window (which is kinda what you'd do if you were designing the part)

I've no idea what's correct here, only that the seal I have fitted works far, far better than the 914rubber 911 "type" seal.

Interesting topic though !

The window scrapper you have fitted is not correct to original spec and doesn’t arrive via Stoddard in Porsche Original spare part packaging.
It might work better than the other one you tried which again is an alternative supplied part and not one supplied by Porsche original parts.
The part number used on Stoddard website is not correct to the factory part!
The number used is for the mounting gutter which did change for the 73 model year; no mention of a left and right side window scrapper as they are sided!

If Porsche change the part during production, however small they did change the part number last two digits to indicate the different versions. Depending on what the part is the last two digits would be either 00 or 10.
The window scrapper part number ends with 10 and indicates that it hasn’t changed through production. If it had changed it would be updated with another number i.e. 11 or 01 for the 00 ending numbers.

On the factory original part diagram for the early doors as well as the late doors; it clearly shows the profile as having the lip on the seal.

One way people can get confused is that over the years and especially in hot climates rubber goes hard.
The lip bit of the window scrapper would be bent up at an angle when mounted and would spit over time and break off all together.
On my first 1.7 this had happened and every time I wound up the window a thin rubber strip would be up the glass.
For those who have never seen the full rubber would never know that it would have had a lip when originally fitted.

Look at your removed window scrappers and study the edge that would be against the glass and you should see that it is not a smooth finish.

Thanks Kev,

I agree entirely with what you have said above, but can you explain this then?

Can I ask an on topic question please?

My Rhs door seal needs replacing, well the bit where the glass guide and quarter light window frame meet the top of the door - there's a little gap appearing here... Does the seal go all the way along the door or is it made of two parts (or three if a little 'plug' between the two is necessary?)

Thanks.

Hi Rod,

Take a look at the last few pages of my 914 restoration thread. The seal for the quarterlight has a small "tail" on it that goes between the aluminium window post and door. Unfortunately from new (on a genuine Porsche seal bought from Porsche centre) the tail is about 3mm too short of reaching the window scraper seal so you get a very tiny gap.
As seals age they also shrink and gaps can appear at each end where once there were none.
I cut my new scraper seal with a little tail on it to close the very gap that I think you are talking about.

My advice would be, if you are replacing the scraper seal (and the new one is overlength) then maybe do the same as I've done.
If your seals are ok and you dont want to replace them them carefully mask top and bottom and fill with a little polyureathane sealant (tiger seal) and with a licked finger smooth off the fillet to match the seal profile eitherside for an almost invisible "gap filler" then remove tape, stand back and admire your handy work. :wink:

Good luck.
