It forms a tight seal between the exhaust manifold and the cylinder head, preventing hot exhaust gases from leaking and causing power loss, noise, or engine damage. Replace this gasket whenever the manifold is removed for service, or if you notice soot tracks, a ticking sound, or signs of an exhaust leak.
