Solution

1. Preparation

Gather tools: socket set, oil catch pan, rags, OBD-II scanner, and flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Address Oil Leak

Locate the Source of the Leak:
- Use a flashlight to inspect the engine and surrounding areas for fresh oil.
- Pay special attention to gaskets (valve cover, oil pan) and seals (front and rear main seals).
Replace Gaskets or Seals:
- If a gasket or seal is found to be leaking:
  - Remove the necessary components to access the gasket/seal.
  - Clean the surfaces with a solvent to ensure proper adhesion.
  - Install the new gasket/seal according to manufacturer specifications, ensuring proper torque.

3. Change Oil If Burnt

Drain Old Oil:
- Position an oil catch pan under the oil pan.
- Remove the drain plug and allow the oil to fully drain.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket of the new filter before installation.
- Install the new oil filter, tightening it by hand.
Add New Oil:
- Replace the drain plug once the old oil has drained completely.
- Add the recommended type and amount of new oil through the oil fill cap.

4. Clean Up

Remove any spilled oil from the engine bay using rags.
Check for any remaining leaks by running the engine and inspecting the areas previously checked.
