- Remove the bolts securing the oil pan using a socket set.
- Gently pry the oil pan off the engine block.
- Scrape off the old gasket material from both the oil pan and engine block surfaces.
- Apply a new gasket or gasket maker as per manufacturer specifications.
- Reattach the oil pan and torque the bolts to the specified torque settings.
Valve Cover Gasket Replacement:
- Disconnect any electrical connections or hoses obstructing access to the valve cover.
- Remove the valve cover bolts using a socket set.
- Lift the valve cover off and replace the gasket.
- Clean the mating surfaces and reinstall the valve cover, torquing the bolts to the manufacturer’s specifications.

3. Refill Oil and Check for Leaks

Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.
Start the engine and let it run for a few minutes while checking for any signs of leaks.

4. Final Checks

Inspect the area around the previously leaking components for any new oil accumulation.
Reconnect the battery and clear any fault codes if necessary.
