For this job, you will need an 8mm and a 10mm socket wrench, a flat-head screwdriver, and a replacement gasket. Remove the protective caps from the bolts on the cylinder head and unscrew the nuts.

Open the oil cap and remove the plastic protections. Lift the retainers of the spark plug connectors and remove the wiring block.

Also, remove all spark plug connectors and their anchoring support. Unscrew all bolts of the valve cover and gently remove it. Carefully remove the gasket from the cover and install the new one, ensuring it adheres perfectly.

Reassemble the cover, ensuring it fits well against the cylinder head. Screw in all bolts and reconnect the spark plug connectors.
