Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Address Oil Leaks

Inspect Gaskets and Seals:
- Remove any components obstructing access to the valve cover and oil filter.
- Inspect the valve cover gasket and oil pan gasket for wear or damage.
Replace Gaskets:
- If damaged, replace the valve cover gasket and/or oil pan gasket.
- Clean the mating surfaces with a gasket scraper and apply a thin layer of gasket maker if necessary.
- Torque the bolts to manufacturer specifications (typically 10-15 ft-lbs for valve cover bolts).

3. Replace Oil Filter and Oil

Drain Old Oil:
- Place a drain pan under the oil pan and remove the drain plug. Allow oil to fully drain.
- Replace the drain plug and torque to specifications (usually around 20-25 ft-lbs).
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Lubricate the rubber O-ring on the new oil filter with fresh oil, then install the new filter.
Add New Oil:
- Pour the appropriate type and amount of engine oil (refer to the owner's manual for specifications).
- Start the engine and let it run for a few minutes, then check for leaks.

4. Final Inspection

After the repairs, visually inspect the engine and surrounding areas for any remaining signs of oil leaks.
Ensure that all tools and materials are removed from the engine bay before closing the hood.
