What adhesive to use to reconnect this..

[1SwtRide]

Hey Pelican Crew

Does anyone know what type of adhesive I should use to reseal these inter-cooler gaskets? Any thoughts are much appreciated!

Clear silicone.

In my experience, silicone does not stick well to rubber - I would clean off the dried silicone that is on there and use superglue - works perfetly on rubber.

I tried the clear silicone to no avail. I'll give super glue a try. Thanks for the helps folks!

I doubt any glue by itself will hold up there for long, seems those are always split like that after a while.
If the rubber isn't old and dried out you could clean it with a rag wetted with laquer thinner or acetone and glue it again with the super glue.
Then if you can push a thick sewing needle through it you could sew the edges together with black braided fishing line to give it more strength. Maybe thats a crazy idea but it might work.

I would try Barges cement. The stuff is really strong. I use it to glue felt to the bottom of my shoes for wading rivers while fishing. BTW I think Jim's sewing idea is a good one if the glue fails. Good luck

I found this PistonHeads link whilst searching for Tiger Seal....some useful input in the 2 pages of comments (as well as some of the predictable daft answers and sharp replies)

Like the idea of superglue, however, it's pointed out in Page 2, that as a cyanoacrylate glue it's not the best when exposed to water (I'm quoting from the thread, not being a smart-arse)

It has got I to be flexible, I don't think "cyano" glue is, or rather, it isn't. My guess would be some sort of cement as well.

Mine looks like it's been repaired with clear silicone (by a PO). At least I thought it was clear silicone (until I read this thread). It's been there for the 9 years I've had the car, so dunno.

Super weatherstripping from 3M? That stuff is hella tough.

You can get 3M weather strip adhesive in black or yellow. The yellow stuff has been around a long time and it's a lot like contact cement in a tube. The black stuff would look better in this location.
If that gasket is petroleum rubber based the solvent based glues like the weather strip adhesive will eat into and merge with the surface of the rubber for good adhesion and if it's silicone rubber based then high temperature silicone adhesive would probably stick to it best.

If you can glue and sew it like I mentioned before and do a neat job of it that might hold it together the longest.

At the same time if you just removed it and forgot about it I really doubt you'd ever notice the car running any different.

Possibly 3M 5200, slow to cure though, will have to find a way to support it.

Nope - the glue/glued seam does not need to be flexible here - the superglue makes a permanent bond between the rubber halves and then the whole thing (sections to the left and right of the seam) flexes as needed (which isn't much).

As Jim noted, the key is to get the seam as "raw" as possible before gluing (completely clean of past adhesives) and not overdoing it on the superglue (don't what a hard, gloppy mess of the stuff on there that can crack) - put a thin coating on one half, press and hold the halves together hard, with your fingers, and in a minute or two, you'll have a bond that looks like it was pulled out of a mold that way and will last permanently.

Another useful tip - if possible, enlist Paul's help with the repair - with the pooftie puffing power that Paul possesses (holy ****, how's that for alliteration?! getcha sum!!! ) he'll blow that MF dry quicker than an air gun delivering 130psi!!!

Was waiting for some welcomed jabs and digs!

Great suggestions everyone. I'll be sure to post up the method I go with and how it comes out when I get some time.

[quattrorunner]

I wouldn't even screw around. I'd use some contact cement after sewing it. Glue us always going to be glue. Sew it and I'd bet it'll stay together.
Jb weld? I'm joking.

Still available from Porsche as a new part?

Clear silicone will work. You need to prep the rubber will grease and wax remover. The same stuff they use on cars prior to painting them.

Using this stuff, I have easily gotten clear silicone to stick to rubber, glass, granite, etc.

Good luck

+1 I used soap to clean the rubber, taped the ends together on the outside, then applied the bead to the inside. Been working over 5 years now.

I've repaired mine twice in 15 years of ownership using clear silicone. Last repair has help up for over 9 years.
