Solution

1. Preparation

Gather tools: socket set, oil filter wrench, clean rags, torque wrench, OBD-II scanner.
Ensure the engine is cool and parked on a level surface.

2. Inspect and Repair Oil Leaks

Sub-step 1: Locate the source of the leak
- Clean the engine area with a degreaser to remove existing oil.
- Start the engine and observe for any new oil leaks.
Sub-step 2: Replace gaskets or seals
- If the valve cover gasket is leaking, remove the engine cover (if applicable) and unscrew the valve cover bolts.
- Replace the old gasket with a new one, ensuring proper alignment.
- Torque the bolts to the manufacturer’s specifications (typically around 10-12 Nm).

3. Change Oil and Filter

Sub-step 1: Drain old oil
- Place a drain pan under the oil pan.
- Remove the oil drain plug with a socket wrench and allow the old oil to completely drain.
Sub-step 2: Replace oil filter
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber seal of the new oil filter with a bit of new oil and install it, tightening by hand.
Sub-step 3: Add new oil
- Reinstall the oil drain plug and tighten it to the manufacturer’s torque specifications (typically around 30 Nm).
- Pour new oil (5W-30 or as specified in the owner’s manual) into the engine via the oil filler cap.

4. Monitor for Additional Issues

After addressing leaks and changing the oil, monitor the engine for any unusual noises or continued burning oil smell.
If issues persist, further inspection may be necessary, potentially involving the turbocharger or piston rings.
