Solution

1. Preparation

Gather tools and materials:
- OBD-II scanner
- Socket set
- Torque wrench
- Oil catch pan
- Clean rags
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Check and Change Engine Oil

Check Oil Level:
- Pull out the dipstick, wipe it clean, reinsert, and pull out again to check the oil level.
- If low, add the appropriate grade of oil (refer to the owner's manual).
Change Oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug with a socket wrench and allow old oil to drain completely.
- Replace the drain plug and torque it to manufacturer specifications (typically around 30 ft-lbs).
- Remove the old oil filter using an oil filter wrench, lubricate the new filter's gasket with clean oil, and install the new filter.
- Fill the engine with the correct type and amount of oil.

3. Address Oil Leaks

Locate Leaks:
- Inspect the oil filter, oil pan, and valve cover gasket for signs of leaking oil.
Replace Gaskets or Seals:
- If leaks are found, replace the corresponding gasket or seal:
  - Remove the affected component (e.g., valve cover).
  - Clean the mating surfaces thoroughly.
  - Install the new gasket or seal, ensuring proper alignment.
  - Reinstall the component and torque to specifications.

4. Clean Up

Wipe down any areas with residual oil, ensuring no oil remains that could cause future burning smells.
Dispose of used oil and filters according to local regulations.
