For this job, you need an 8mm and a 10mm socket wrench, a flathead 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 locks of the spark plug connectors and remove the wiring harness.

Also, remove all spark plug connectors and their mounting bracket. Unscrew all the bolts of the valve cover and gently remove it. Carefully take off the old gasket from the cover and install the new one, ensuring it adheres perfectly.

Reattach the cover, making sure it fits snugly against the cylinder head. Reinstall all the bolts and reconnect the spark plug connectors.
