Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Identify and Repair Oil Leaks

Inspect Seals and Gaskets:
- Remove engine covers if necessary.
- Inspect the valve covers, oil pan gasket, and any other seals for leaks.
- Replace any damaged gaskets or seals with new ones.
Check Oil Filter and Drain Plug:
- Use an oil filter wrench to remove the oil filter.
- Inspect the filter for leaks; replace if necessary.
- Tighten or replace the drain plug if oil is leaking from it.

3. Change Engine Oil

Drain Old Oil:
- Place a drain pan under the oil pan.
- Remove the drain plug and allow the old oil to drain completely.
Install New Oil Filter:
- Apply a small amount of new oil to the rubber gasket of the new oil filter.
- Install the new oil filter by hand-tightening it.
Add New Oil:
- Replace the drain plug and tighten to the manufacturer's specifications (typically around 25-30 Nm).
- Pour the recommended type and amount of new engine oil through the oil filler cap.

4. Reassembly and Final Checks

Reconnect the battery.
Start the engine and allow it to run for a few minutes.
Check for leaks around the oil filter and drain plug.
Ensure the oil pressure is normal and the engine runs smoothly.
