Manifold Gasket Replacement

June 18, 2009

Well, the exhaust manifold leak never did get any better. Rather than try and mess with the old gasket I bought a new one.  At the same time I replaced the exhaust pipe flange nuts with stainless ones.

Getting the manifold out is a pain with the engine in the car but I had it out inside of an hour.  We were leaking some gas here.
There was  a little leaking on the #1 cylinder too.

Here is he old and new gaskets.  The old gasket was a metal crush gasket.  Once the hot exhaust gas started leaking past the gasket it was toast.  The new gasket is a fiber type.  I used a high-temp copper spray sealant on it too.  I did not take after pictures but it looks good now.
