Solution

1. Preparation

Gather tools and materials: clean rags, oil catch pan, socket set, torque wrench, and replacement oil/filter as needed.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Replace Oil Filter

Locate the oil filter; it may be necessary to remove any engine covers.
Use an oil filter wrench to remove the old oil filter.
Clean the mounting surface on the engine and apply a small amount of new oil to the rubber seal of the new filter.
Install the new oil filter by hand, tightening it according to the manufacturer's specification (usually 3/4 to 1 turn after hand-tight).

3. Address Oil Leaks

If leaks are found from the valve cover gasket, remove the valve cover by:
- Unbolt the valve cover using a socket set.
- Remove any old gasket material from the surface.
- Install a new gasket, ensuring proper alignment.
- Reinstall the valve cover and tighten bolts to specification (typically 10-12 Nm).

4. Add Oil

If the oil level is low, add the appropriate type and grade of engine oil as specified in the owner's manual.
Use a funnel to avoid spills and ensure the correct amount is added.

5. Clean Up

Remove any spilled oil with rags and dispose of used oil and filters properly.
Reconnect the battery.
