Hi Everyone,

Bit of a random question - but could someone please suggest the best type of glue to stick the foam/rubber type material back on to my engine cover. I had it off over Christmas while cleaning and sealing the sills etc and the foam bit fell off.

My concern is - Do i need a high temperature glue?

Thanks

Mark

I can't recommend a particular brand, but would have thought a high temp, oil resiliant based adhesive.
I'm sure some one will cherp up with one ;)
 
thanks for the replies. Yes, i plan to put it back on. i've actually been reading about the merits of keeping it off, but i'm usually of the opinion - If Porsche put it there, then it needs to stay there.
I wont be doing any track days or serious hard driving.
 
Fair enough! Makes sense. In which case it makes sense to use a heat resistant one as you say. I dont know if Wurth do one? As most of the stuff on the cars of that era was from Wurth, it may be a place to start.
 
It's a long since I took mine off but I don't remember seeing any foam on it. May be it had just disintegrated over time. I'm not sure. Which makes me ask, do you need to put the foam back on? May be just put it back on without it?
 
Its a good plan Steve - if it develops an oil leak i guess i would see it quicker if i have no foam.....then again...i don't really want to know about any dreaded oil leaks lol. The foam will help me sleep better at night.
 
The foam is like a "skinned" polyurethane moulding-when made they have an outer skin which sets smooth with a foamed interior,very much like the cushions on operating tables-my guess is they are intended to damp out noise & stop the undertray vibrating against the engine casing at higher speeds.
I would have thought that Evostick would be good or a single pack polyurethane seam sealant.
 
I think the foam was necessary for the sound requirements for the Swiss market....my 964C4 had foam -that undertray now in ChrisW's loft!
 
Interesting fact about swiss regulations. It would take a lot of foam to dull the note from the cup pipe :)
 
My undertray is up in the garage rafters. It seems happier there than catching oil, a job left to a mat under the car when it's parked.

Wouldn't Tiger Seal or Gripfill work to stick the foam on?
