Solution

1. Preparation

Tools Required: Socket set, rags, OBD-II scanner, flashlight.
Safely park the vehicle on a flat surface and allow the engine to cool.
Disconnect the negative battery terminal to ensure safety during inspection.

2. Identify and Fix Leaks

Inspect Gaskets and Seals:
- Check the valve cover gasket and oil pan gasket for leaks. If damaged, replace as follows:
  - Remove any components obstructing access to the gasket.
  - Unbolt the valve cover or oil pan, clean the surface, and replace the gasket.
  - Reinstall the cover or pan, ensuring proper torque specifications (typically 10-15 lb-ft).
Check Oil Filter and Drain Plug:
- Tighten the oil filter and drain plug if they are loose. Replace if damaged.

3. Change Oil if Necessary

If the oil is burnt or contaminated:
- Drain Old Oil:
  - Remove the drain plug and let the oil drain completely into a pan.
- Replace Oil Filter:
  - Remove the old oil filter with an oil filter wrench. Lubricate the O-ring of the new filter and install it.
- Refill Engine Oil:
  - Reinstall the drain plug and refill the engine with the manufacturer-recommended oil type (5W-20 or equivalent).
  - Check the oil level after filling and adjust as necessary.

4. Clean Up and Test

Clean any spilled oil with rags and ensure all tools are removed from the engine bay.
Reconnect the battery terminal and start the engine to check for leaks and listen for abnormal noises.
