Solution

1. Preparation

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

2. Identify and Repair Leak Source

Inspect Gaskets and Seals:
- Remove any engine covers if necessary.
- Check the valve cover gasket for cracks or wear. Replace if damaged.
- Inspect the oil pan gasket and replace if leaking.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new oil filter with new oil, then install it.
- Tighten to manufacturer specifications (usually hand-tight plus a quarter turn).

3. Clean Affected Areas

Use an engine degreaser to clean any oil residue from the engine bay.
Rinse and allow to dry before starting the vehicle.

4. Refill Engine Oil

Ensure the correct oil type is used (check owner’s manual for specifications).
Replace the drain plug and tighten to specification (usually 20-30 Nm).
Refill the engine oil through the oil filler cap.

5. Final Checks

Reconnect the battery and start the engine.
Check for any leaks immediately after starting.
Monitor oil levels and ensure the engine runs smoothly without burning odors.
