Solution

1. Preparation

Gather necessary tools and parts.
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 Leaks

Inspect Gaskets and Seals
- Use a wrench to remove components obstructing access to the valve cover gasket.
- Replace the valve cover gasket if oil is leaking from it.
- Torque specifications: Typically around 10-15 Nm (consult service manual for exact values).
Check Oil Filter and Drain Plug
- Tighten the oil filter if loose; replace it if damaged.
- Inspect the drain plug for leaks; replace the washer if necessary.

3. Clean Up

Use an engine degreaser to clean any oil residue from the engine bay.
Ensure all components are dry and free from oil to prevent false diagnostics in the future.

4. Refill Engine Oil

If oil levels were low, refill with the appropriate type and grade of oil as specified in the owner’s manual.
Check for proper oil level with the dipstick after refilling.
