Solution

1. Preparation

Tools Required: Socket set, oil catch pan, rags, OBD-II scanner
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery to avoid any electrical shorts.

2. Identify the Source of the Leak

Sub-steps:
1. Remove any engine covers if necessary for access.
2. Use a flashlight to inspect the engine thoroughly for oil leaks.
3. Clean any visible oil spots with a solvent to identify the source of the leak.

3. Replace Faulty Components

Sub-steps:
1. If the oil filter is leaking, replace it:
  - Use an oil filter wrench to remove the old filter.
  - Lubricate the rubber gasket of the new filter with fresh oil and install it, tightening it to the manufacturer’s specifications (usually hand-tight plus a quarter turn).
2. If the valve cover gasket is leaking, follow these steps:
  - Remove the bolts securing the valve cover using a socket set.
  - Carefully lift the valve cover, removing the old gasket.
  - Clean the mating surfaces thoroughly.
  - Place the new gasket on the valve cover, then reattach the cover and tighten the bolts to the specified torque (typically around 10-15 ft-lbs).

4. Check Oil Levels and Top Off

Sub-steps:
1. Refill with the appropriate type and grade of oil if low.
2. Use the dipstick to ensure the oil level is within the safe range.

5. Reassemble and Test

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle, checking for any leaks or unusual noises.
3. Conduct a test drive to ensure that the burning oil smell has dissipated.
