Exhaust manifold sealant

[Stan Thomas]

I have a classic car which has a three-part exhaust manifold which "telescopes" together - but I do not know how it was sealed or whatever jointing was used (but no longer available anyway).

The problem therefore is what can I use for jointing, which would then require the thee parts to be pressed together as the whole asssembly as it is slid onto the studs.

Can anyone suggest a compressable material - or a very high temperature silicone type sealant which would handle the heat but remain sufficiently flexible to allow for thermal expansion and contraction etc.

Best suggestion gets a (slow) ride in a sleeve valve Daimler!!!

Whilst I can't help with the answer, have you tried looking online for an owner's club/forum?

Something like this should work.

That won't work, it is just an RTV "silicone" type instant gasket.

Whilst it is fantastic on rocker covers, sumps etc, it will not work on an exhaust.

TBH, I can't get my head round the concept of a telescopic exhaust manifold, can you get a pic?

A tube of exhaust pipe sealant is available at most motor factors
White, helps the pipes slide together then expands to fill any gaps when hot
