Tools Required: Socket set, torque wrench, gasket scraper, new valve cover gasket.
Remove valve cover bolts using a socket set.
Carefully lift the valve cover off and remove the old gasket.
Clean the mating surfaces with a gasket scraper to remove old gasket material.
Place the new gasket onto the valve cover and re-install it, tightening the bolts to specified torque (typically 7-9 lb-ft).

4. Repairing Oil Pan Gasket

Tools Required: Socket set, torque wrench, gasket scraper, new oil pan gasket.
Drain the engine oil using an oil catch pan.
Remove the oil pan bolts and carefully take off the oil pan.
Remove the old gasket and clean the surfaces thoroughly.
Place the new oil pan gasket and reattach the oil pan, tightening bolts to manufacturer specifications (usually 7-9 lb-ft).
