Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, rags, oil catch pan, flashlight.
Allow the engine to cool before starting any work. Disconnect the battery if working on electrical components.

2. Identify and Repair Leaks

Sub-steps:
1. Clean the engine bay with degreaser to identify the source of the leak more easily.
2. If leaks are found, tighten or replace any loose or damaged components (e.g., oil filter, drain plug).
3. Replace any faulty gaskets or seals identified during inspection (e.g., valve cover gasket, oil pan gasket).
4. Ensure all components are torqued to manufacturer specifications (consult repair manual for specific torque values).

3. Replace Engine Oil and Filter (if necessary)

Sub-steps:
1. Place the oil catch pan under the oil pan and remove the drain plug to drain old oil.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to the specified value.
4. Fill the engine with the recommended type and amount of engine oil (refer to owner’s manual).
5. Start the engine and let it run for a few minutes, checking for leaks.

4. Monitor and Test

Sub-steps:
1. After repairs, take the vehicle for a test drive to ensure the burning oil smell does not return.
2. Check the oil level again after the test drive to ensure it remains stable.
3. Re-scan for error codes to confirm no new issues are present.
