MS 90509 Fel-Pro Gaskets Exhaust Manifold Gasket

Fel-Pro® gaskets offers 100 Percent vehicle sealing with application-specific materials to give you sealing solutions with the performance and durability professionals trust. Many new engines are assembled without exhaust manifold gaskets. Since the castings are new and machined surfaces are smooth, the exhaust manifold can fit tightly against the cylinder head without leaks. After prolonged use with high exhaust temperatures and numerous heating/cooling cycles, the manifold sealing surfaces may warp and corrode. Even just removing the manifold may slightly warp it. So when servicing the manifold, there is a good chance that an exhaust manifold gasket will be required to provide an effective seal. Because of the expansion and contraction from the heating/cooling cycles, many exhaust manifold gaskets are constructed with a fiber facing material on one side and perforated steel on the other. When this is the case, the steel face of the gasket is installed toward the exhaust manifold, with the fiber surface against the cylinder head. This allows expansion and contraction of the exhaust manifold to take place without damaging the fiber side of the gasket. This design seals the exhaust manifold while allowing it to move on the metal surface of the gasket, just like it does on the metal surface of the cylinder head in the absence of a gasket.
