Tools Required: Gasket scraper, torque wrench, socket set.
Remove any components obstructing access to the valve cover or oil pan (e.g., intake manifold, engine covers).
Remove the valve cover or oil pan bolts using the socket set.
Carefully lift off the component and remove the old gasket using a gasket scraper.
Clean the surfaces thoroughly to remove any residue.
Place a new gasket in position and reattach the valve cover or oil pan, tightening bolts to the specified torque values.

3. Refill Engine Oil

Tools Required: Funnel, oil catch pan.
After repairs are complete, refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
