The camshaft cover gasket for the Citroën 15CV is an essential component that ensures a proper seal between the camshaft cover and the cylinder head. This gasket prevents oil leakage from the upper engine compartment, which is crucial for protection against contamination and engine damage. Often made from high-quality materials such as cork, rubber, or silicone, this gasket withstands high temperatures and pressure. A well-functioning gasket contributes to optimal engine performance and extends the lifespan of engine components in the classic Citroën 15CV models.
