Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during inspection.

2. Identify and Repair Leaks

Inspect Gaskets and Seals
- Use a flashlight to locate any oil seepage from gaskets or seals.
- Replace any worn or damaged gaskets or seals (e.g., valve cover gasket, oil pan gasket).
Check Oil Filter and Drain Plug
- Tighten the oil filter and drain plug using an appropriate wrench.
- If damaged, replace the oil filter and drain plug with new ones.

3. Clean Up

Remove Excess Oil
- Use rags or absorbent materials to clean up any spilled oil around the engine bay and under the vehicle.
- Ensure all residual oil is removed to prevent future burning smells.

4. Refill Engine Oil

Check Oil Level
- If oil was low, refill with the appropriate type and grade of oil as specified in the owner's manual.
- Use a funnel for precision and avoid spills.

5. Reassemble and Test

Reconnect the battery.
Start the engine and let it idle while observing for any further leaks or burning smells.
Conduct a short test drive to ensure the issue is resolved.
