Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Identify and Repair Leaks

Inspect Gaskets and Seals:
- Remove any engine covers as necessary.
- Use a clean cloth to wipe around suspected leak areas.
Replace Damaged Gaskets or Seals:
- If leaks are found at gaskets (e.g., valve cover, oil pan), remove the old gasket.
- Clean the surfaces thoroughly with a gasket scraper.
- Apply a new gasket or sealant according to the manufacturer's specifications and reassemble.

3. Replace Oil Filter (if necessary)

Remove Old Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
Install New Oil Filter:
- Lubricate the rubber O-ring of the new filter with fresh oil.
- Install the new filter hand-tight and ensure it is secure.

4. Change Engine Oil

Drain Old Oil:
- Place an oil catch pan under the oil pan, remove the drain plug, and allow the old oil to drain completely.
Refill with Fresh Oil:
- Replace the drain plug and tighten to specifications (usually 20-25 ft-lbs).
- Add new oil through the oil filler cap (consult owner’s manual for the correct oil type and capacity).

5. Clean Up

Dispose of Old Oil:
- Take the used oil and oil filter to a recycling center.
Check for Residual Oil:
- Inspect the engine bay for any residual oil and clean as needed.
