Just replaced my main oil seal and rebuilding the engine (LIS GT186). The new gasket set I've purchased has a thick gasket material type exhaust gasket, I've always used copper gaskets before, is there any reason I should not use the provided gasket?

There is no reason you can't use it,but they are not as good as a copper faced one.To be honest, for a couple of quid i'd personally buy a separate copper faced one.Some years ago on a cast cylinder,i used to use a solid copper gasket that Dave Webster used to make.They were re useable and never blew.Cheers,Speedy.

Is it solid, or one of the ones that bends when it's tightened?

don't the solid ones need annealing when using/re-using?Muttley McLadd wrote:Mag to grid..

That's less effort than a rebore/piston/crank/head change because the cheese one has disintegrated at 75mph in the outside lane of the motorway.mickdale wrote:don't the solid ones need annealing when using/re-using?
The downpipe on my clubman is made in such a way that the head cowling comes off without the need to loosen the exhaust. There's no reason to remove the downpipe that I can think of.

Someone once told me to heat up the solid copper gasket until cherry red and then allow to cool. I totally feckin ignored him, and linnished both sides of the solid copper gasket on a piece of glass with wet 'n dry taped to it, to ensure it was perfectly flat. I do this to the U bend exhaust gasket face too to ensure I get the best seal possible. Also a smear of high temperature silicon on all faces.mickdale wrote:don't the solid ones need annealing when using/re-using?Muttley McLadd wrote:Mag to grid..

It's the opposite for copper. Heat then cool with cold water. Makes it softer. I anneal my copper soft jaws on my vice like that.
Your best leak prevention is from surfacing your exhaust flange (either a stub or U bend).
