- Unbolt the valve cover carefully to avoid warping.
- Clean the mating surfaces thoroughly using a gasket scraper and solvent.
- Apply a new valve cover gasket, ensuring it is seated properly.
- Reinstall the valve cover and torque bolts to manufacturer specifications.

3. Replace Oil Filter

Oil Filter Replacement
- Locate the oil filter and use an oil filter wrench to remove it.
- Before installing the new filter, apply a small amount of oil to the rubber gasket on the new filter.
- Install the new oil filter by hand until snug, then tighten according to the manufacturer’s specifications.

4. Add Oil

Top Off Engine Oil
- Remove the oil filler cap and add the appropriate type of oil recommended in the owner’s manual.
- Use a funnel to prevent spills and check the oil level using the dipstick to ensure it is within the proper range.

5. Testing

Run Engine and Check for Leaks
- Start the vehicle and let it idle for a few minutes.
- Observe for any signs of oil leaks or unusual noises.
- Monitor the oil pressure gauge to ensure it reads within the normal range.
