Function of the Exhaust Manifold Gasket
The exhaust manifold gasket provides a leak-free seal between the cylinder head and the exhaust manifold. It prevents exhaust gas leaks, protects engine components from excessive heat, and helps maintain proper exhaust gas flow.
A worn or damaged gasket may cause exhaust leaks, increased engine noise, exhaust gases to escape into the engine compartment, reduced engine performance, and an increased risk of damage to adjacent components.
