Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the engine is cool and disconnect the battery.

2. Inspect for Leaks

Clean the engine bay with a degreaser to remove any existing oil.
Start the engine and let it idle, observing any new oil leaks.
Use a flashlight to examine areas around the oil filter, valve covers, and oil pan.

3. Replace Damaged Gaskets or Seals

If a leak is detected at the valve cover gasket:
- Remove any components obstructing access to the valve cover.
- Unscrew and remove the valve cover.
- Clean the mating surfaces with a gasket scraper.
- Install a new valve cover gasket and reassemble.
If the oil filter is leaking:
- Use an oil filter wrench to remove the old filter.
- Lubricate the rubber gasket on the new filter with fresh oil.
- Install the new filter and ensure it is tightened properly.

4. Address Oil Level Issues

If the oil level is low:
- Remove the oil fill cap and add the appropriate type of engine oil to reach the correct level.
- Check for proper oil viscosity as per manufacturer specifications.

5. Test and Clean

Allow the vehicle to run for a few minutes and check for any further leaks.
Clean any spilled oil using degreaser and rags.
