Clean the mating surface of the oil pan and the engine block using a scraper to remove old gasket material.
Apply a new gasket or gasket maker as per the manufacturer’s specifications.
Reinstall the oil pan and torque the bolts to the specified torque values (typically around 10-12 ft-lbs, verify with service manual).
Refill the engine with the appropriate type and amount of oil.

4. Replace Valve Cover Gasket (if necessary)

Tools Required: Socket set, torque wrench, sealant (if specified)
Remove the engine cover (if applicable) and disconnect any components obstructing access to the valve cover.
Remove the valve cover bolts using a socket set and carefully lift off the valve cover.
