Carefully lift the valve cover away from the engine.
Clean the mating surfaces on both the valve cover and engine block with a suitable solvent.
Place the new gasket on the valve cover, ensuring it fits into the grooves correctly.
Reinstall the valve cover and torque the bolts to the manufacturer’s specifications (usually around 7-9 ft-lbs).
Reinstall any removed components.

Locate the oil filter under the vehicle.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the gasket of the new filter.
Install the new oil filter by hand, tightening it according to the manufacturer's specifications.

4. Repair Oil Pan Leak (if applicable)

Drain the engine oil using a drain pan by removing the drain plug.
Remove the oil pan by unscrewing the bolts that secure it to the engine block.
Clean the old gasket material from the oil pan and engine block surfaces.
Install a new oil pan gasket and reattach the oil pan, torquing the bolts to specifications.
Reinstall the drain plug and refill the engine with new oil.
