Replacing the gasket is a delicate operation, so it is recommended for experienced individuals. Start by removing all components above the engine to facilitate the removal of the valve cover.

Remove the engine covers, the electrical connections for the spark plugs, the spark plugs themselves, the intake hose, the timing chain cover, and everything connected to the cover, carefully setting aside the removed components. At this point, remove all the bolts from the cover and take it off. Replace all the rubber gaskets and install the new gasket, ensuring it adheres properly.

Clean the engine head thoroughly where the gasket will adhere. Carefully reassemble the cover and all previously removed components.
