Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool if it has recently been operated.

2. Identify and Repair Oil Leaks

Inspect Gaskets and Seals
- Use a flashlight to closely examine the valve cover gasket and oil filter seals.
- If any gasket or seal shows signs of wear or damage, replace it.
Replace Damaged Components
- Tools Required: Socket set, torque wrench, gasket scraper.
- Remove the valve cover or oil filter as necessary to access the gasket.
- Clean the mating surfaces with a gasket scraper.
- Install a new gasket or seal, ensuring proper alignment.
- Torque to manufacturer specifications (typically between 10-15 ft-lbs for valve covers).

3. Change Oil and Filter

Drain Old Oil
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and allow the old oil to drain completely.
- Tools Required: Socket set, oil drain pan.
Replace Oil Filter
- Remove the old oil filter using an oil filter wrench.
- Lubricate the rubber O-ring on the new filter with a bit of new oil.
- Install the new oil filter by hand, ensuring it is snug but not over-tightened.
Add New Oil
- Replace the drain plug and torque to manufacturer specifications.
- Add fresh oil through the oil filler cap, using the recommended type and quantity as per the owner’s manual.

4. Final Checks

Inspect the engine bay again for oil leaks after running the engine for a few minutes.
If any leaks persist, re-evaluate the gaskets and seals.
