Solution

1. Preparation

Tools Required: Socket set, oil catch pan, rags, OBD-II scanner
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues while working.

2. Address Oil Leaks

Inspect and Replace Gaskets:
1. Remove any engine covers if necessary to access leaking gaskets.
2. Clean the surface around the gasket with a rag.
3. Replace the gasket with a new one, ensuring it is properly seated.
4. Reinstall any removed components, tightening to manufacturer specifications.
Inspect and Replace Oil Filter:
1. Place an oil catch pan under the engine.
2. Remove the old oil filter using an oil filter wrench.
3. Apply a small amount of new oil to the rubber O-ring of the new filter.
4. Install the new oil filter, tightening it hand-tight.

3. Change Engine Oil

Place an oil catch pan under the oil pan.
Remove the drain plug using a socket set and allow the old oil to drain completely.
Replace the drain plug and tighten it to specification.
Add new engine oil through the oil filler cap, using the recommended type and amount specified in the owner's manual.

4. Verify and Test

Reconnect the battery.
Start the engine and let it idle, checking for leaks and the burning smell.
Take the vehicle for a short drive to ensure normal operation and check for any further odors.
