Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the engine is cool.

Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new filter with clean oil.
- Install the new filter and tighten to manufacturer specifications (usually hand-tight).
Valve Cover Gasket:
- Remove any components obstructing access to the valve cover.
- Unbolt the valve cover using a socket set and carefully lift it off.
- Remove the old gasket and clean the mating surfaces.
- Install the new gasket and reassemble by torquing to manufacturer specifications.

4. Check for Additional Leaks

After replacing components, start the engine and allow it to idle.
Monitor for any new leaks around the replaced areas.

5. Finalize and Clean Up

Dispose of any used oil and filters according to local regulations.
Clean up any spills or residues around the work area.
