Valve Cover Gaskets:
- Remove any components obstructing access to the valve cover.
- Unbolt the valve cover and remove it carefully.
- Clean the mating surfaces of the engine and the valve cover.
- Install new valve cover gaskets and reassemble the valve cover, tightening bolts to the specified torque.
Oil Pan Gasket:
- If the oil pan gasket is leaking, remove the oil pan by unbolting it.
- Clean the oil pan and engine surfaces thoroughly.
- Install the new oil pan gasket, ensuring proper alignment.
- Reattach the oil pan and torque the bolts to the specified value.

4. Refill Engine Oil

Pour the appropriate type and amount of new engine oil into the engine using a funnel.
Replace the oil cap securely.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes while checking for leaks.
Monitor the oil pressure warning light on the dashboard.
