Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, OBD-II scanner, cleaning rags.
Safety Warnings: Allow the engine to cool before beginning work. Always wear safety glasses and gloves.

2. Address Oil Leaks

Identify leak sources: Use a flashlight to locate the source of oil leaks (e.g., valve cover gasket, oil pan gasket).
Replace gaskets/seals: Remove the old gasket/seal and clean the surfaces. Apply a new gasket or sealant and reassemble.
- Torque values: Refer to the vehicle's service manual for specific torque specifications when tightening bolts.

3. Change Engine Oil

Drain old oil: Position an oil catch pan under the oil pan, remove the drain plug, and allow the oil to drain completely.
Replace oil filter: Remove the old oil filter using an oil filter wrench and install a new one, applying a small amount of oil to the rubber gasket.
Add new oil: Replace the drain plug and fill the engine with the appropriate type and amount of oil as specified in the owner's manual.

4. Inspect and Clean Components

Clean engine area: Use cleaning rags to wipe away excess oil and dirt from the engine compartment to prevent future issues.
Check hoses and wiring: Inspect rubber hoses and electrical wiring for signs of wear or damage that may contribute to burning smells.
