Solution

1. Preparation

Gather tools: socket set, torque wrench, oil catch pan, rags, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues during repairs.

2. Identify and Repair Oil Leaks

Inspect Gaskets:
- Remove engine covers if necessary to access the valve cover and oil pan gaskets.
- Check for cracks or deterioration on the gaskets.
- If damaged, remove the old gaskets and clean the surfaces.
Replace Gaskets:
- Install new valve cover and oil pan gaskets. Ensure proper orientation and alignment.
- Torque bolts to manufacturer specifications (usually around 10-15 Nm for valve cover bolts; check specific values for your model).

3. Clean Up and Replace Oil

Clean Leaked Oil:
- Use rags to clean any oil residue in the engine bay to prevent further burning.
Change Oil:
- If oil level is low, drain any old oil using an oil catch pan.
- Replace with the correct type and amount of engine oil (usually 5W-30 or as specified).
- Replace the oil filter if necessary, ensuring the rubber O-ring is properly seated.

4. Final Checks

Reconnect the battery.
Start the engine and run for a few minutes while checking for leaks.
Monitor the engine for any abnormal sounds or smells.
