Solution

1. Preparation

Tools Required: Rags, oil catch pan, socket set, torque wrench, OBD-II scanner.
Ensure the engine is off and cool before beginning any work. Disconnect the battery for safety.

2. Identify and Repair Leaks

Sub-steps:
1. Clean the engine bay with a degreaser to remove any old oil residue.
2. Use a flashlight to inspect for leaks around the oil filter, oil pan, and valve cover.
3. Replace any leaking gaskets (valve cover gasket or oil pan gasket) as necessary:
  - Remove the affected component (e.g., valve cover) by loosening bolts with a socket set.
  - Clean the mating surfaces thoroughly.
  - Install a new gasket and torque bolts to the manufacturer’s specifications (typically 7-10 ft-lbs).

3. Change Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan and remove the drain plug to allow old oil to drain completely.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to specifications (usually around 20-25 ft-lbs).
4. Fill the engine with the correct type and amount of oil (typically 0W-20 for this model).

4. Monitor and Test

Sub-steps:
1. Reconnect the battery and start the engine.
2. Allow the engine to reach operating temperature while monitoring for leaks or unusual smells.
3. Take the vehicle for a short test drive to ensure the issue has been resolved.
