Re: Sealing Manifold Gaskets???

Keep in mind that the exhaust manifold gets much hotter than the intake manifold and engine block and thus expands more than the block it's mounted to. If used, a sealant will try to resist that movement which can lead to early gasket failure most especially with the composite gasket type.
