3. Replace Valve Cover Gasket

Sub-steps:
1. Remove any components obstructing access to the valve cover (e.g., ignition coils, wiring harness).
2. Unbolt the valve cover and carefully lift it off, ensuring not to damage the gasket surface.
3. Clean the valve cover and cylinder head surfaces thoroughly.
4. Install a new valve cover gasket, ensuring it is seated properly.
5. Reinstall the valve cover and torque to specifications.

4. Check Oil Filter and Drain Plug

Sub-steps:
