Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working near electrical components.

2. Identify the Source of the Leak

Oil Filter Inspection
- Remove the oil filter using an oil filter wrench.
- Check the rubber O-ring for damage; replace if necessary.
Oil Drain Plug Inspection
- Use a socket wrench to check the tightness of the oil drain plug.
- If it’s loose, tighten to the manufacturer's specifications (typically 20-25 ft-lbs).
Gasket Replacement
- If the valve cover gasket is leaking, remove the valve cover by loosening the bolts with a socket set.
- Clean the mating surfaces and replace the gasket with a new one, ensuring proper alignment.

3. Repair and Clean-Up

Replace the Oil Filter
- Apply a small amount of fresh oil to the new oil filter's O-ring.
- Install the new oil filter, tightening it by hand (do not over-tighten).
Refill Oil
- If oil was lost, refill with the recommended oil type as per the owner’s manual (usually 5W-20 or 0W-20).
- Start the engine and let it run for a few minutes, then check for leaks.

4. Final Checks

Check the oil level again with the dipstick and add oil if necessary.
Clean any spilled oil from the engine bay and under the vehicle to prevent confusion with future leaks.
