Gaskets
beetleboy88 - June 4th, 2011 at 12:17 PM
Hey guys. Been told by my mechanic I need new gaskets on the exhaust. Problem is I have the single pack quiet tip and can't find anywhere that
gaskets for them. Am I better off going to a specialist muffler exhaust place and let them fix it up or do I keep looking for gaskets on the net??
Cheers!

Have you tried Mick Motors etc ?
Vintage Vee Dub in Sydney?
I would send emails to the VW shops that advertise on VWMA magazine.. for a Gasket ... OR
You can Use normal Silastic on the exhaust system..
I use the black one as it doesn't look out of place but none of them burn...
undo the offending joint...
clean it .. very clean... wire brush... etc..
then cover the joint with about 5mm+ of SILASTIC...
let it nearly dry.. then do up the bolts leaving a small gap ..
and let it go hard...
then tighten the bolts... and no more leaks ..
proven to work... I use it on My exhaust gaskets...
[I was told about it by an exhaust mechanic who used it when fitting new headers]
cheers

PS: VWs don't like even very small exhaust leaks...

If you're finding it too hard to get a gasket you can always buy gasket paper and cut your own. Or indeed just cut it out of a cornflakes box.
Seriously!

[size=4]NOT for an exhaust gasket
they need to be fire/burn proof...
Asbestos was the best material for exhaust gaskets..
but its now illegal to buy them...
they were nice and thick...
Silastic is the best gap filler that won't burn up...

Lee, you can go to any parts store and buy exhaust gasket. That's the one with metal backing on it. I have bought some and made gaskets for my Baja
before from Repco.
The only issue it cutting it, you need a really sharp knife or good kitchen shears. Then for the exhaust hole I used a hole punch. I took the largest
one out of my kit and punched around the inside of the exhaust hole. Just like a bought one.
I would also not recommend using silastic when you can buy tubes of exhaust specific gasket maker for basically the same cost. I have using Maniseal
before (also Repco) with great results. Comes in a tube that looks like a fat tube of toothpaste. Apply to the surfaces and bolts together. Then the
heat of the exhaust when the car is running cures the gasket.

I ave used exhaust specific gasket goo before and found that silicon was the best. I think some froen on it but eh, i leak free sonuds soooo mu ch
better.

What gaskets are you chasing,the head to manifold,lower tubes or muffler to header? Do the lower pipes use a flange or the old round gasket?

thanks for all the helpful info guys. I will go into super cheap tomorrow and suss it all out.

When making silicone gaskets, Don't just smear it on the mating surfaces.
squeeze an even sized bead around every hole, ie pipe, bolt hole etc.
When offering up surfaces, be careful not to disturb the bead (this can be very tricky)
As you tighten up the bolts the silicone bead should compress and spread out but not squeeze out.
Tighten the flange up with two or three washers in between to maintain an even spacing and hold everything in place.
Give it a good time to go off (a day or three), remove the washers and retighten.
This will never leak again!
It is a little known fact that Alan Moffat's engines (remember the ford's with DOW on the doors?) were assembled with no gaskets, just silicone.

I remember that the silicone got into the oil galleries and he had some monumental blow ups.
I have gaskets if you can tell me which ones you require.

any exhaust shop will have them hanging on a hook. If for some reason they dont they will have the material and punches to make one in 30 seconds.
They'll have oxy to heat up the nuts to take them off. They'll have sealant and they'll have your car on the hoist and in the air and be done in 15
minutes.
Alternatively you can stuff about lie on the floor, curse and scream, skin your knuckles, potentially break an exhaust stud and spend 2 days repairing
it, and then maybe put your exhaust back on without a leak.
Some things are worth just putting out the bucks.

[size=4]exhaust gasket cement is rubbish...
it goes hard as...
and then cracks and falls out or in.... lol
Silastic will take the pressure , be flexible and WILL stop ALL exhaust leaks...
If You have a semi standard VW its a great product...
make sure the surfaces are CLEAN...

Sure he had some issues, but he also won a few. With no gaskets!
Amazing stuff!

I was a Moffatt fan but he would have won more without Dow Corning sponsorship or Gricey bashing!

Moffat, a winging self opinionated Yank I used to think, then I googled and found out this...................born 10 November 1939 in Saskatoon,
Saskatchewan, Canada.................. so he must have been a top fella as he was Canadian and born EXACTLY 10 years before me (depending on the time
of day obviously) I forgive you Mr. Moffat
