I've done a few V6 exhaust manifold gaskets and have always used the metal ones that Vaux supply. All of the old ones I have removed are the composite type. Do the metal ones last for life or have any of you had to replace them?

Also I've only ever had to do one N/S gasket. Is it mainly the O/S that fails?

I have doen the odd nearside gasket to....

The metal ones are MUCH better, if you check and flatten the manifold surface when re-fitting with a metal one, they never seem to fail again.

Metal gaskets should be the best as they reduce dramatically the bolt relaxation that occurs with the traditional composite type gasket. To ensure long lasting results as Mark very correctly mentioned you need a flat and nicely finished surface and you need to do a 3 stage torqueing of the bolts with the final tightening being +3NM more than the nominal value. It will never ever leak again.
