Mazda 3 Rocker cover gasket replacement
Why are Mazda 3 rocker cover gaskets replaced?
The engine in your Mazda 3 relies on oil to keep the valvetrain components at the top of the engine well lubricated.
To keep this oil inside the engine and to keep dirt and debris out, a valve cover (also known as a rocker cover or tappet cover) is used with a rubber or cork gasket.
This gasket can fail over time, as it is exposed to severe heat and oil, and will need to be replaced periodically to prevent oil leaks and damage to these sensitive engine components.
Rocker Cover gasket replacement can cost between $200 and $800, depending on the location of the rocker cover and if the inlet manifold needs to be removed to allow access.
