Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Repair Leaks

Sub-steps:
1. Remove any engine covers if necessary for access.
2. Use a flashlight to inspect for oil leaks around the oil pan, valve cover, and oil filter.
3. If leaks are found, clean the area with a suitable degreaser and a cloth.
4. Replace any worn or damaged gaskets or seals (e.g., valve cover gasket, oil pan gasket).
5. Reinstall removed components and ensure all fasteners are properly torqued.

3. Addressing Oil Burning

Sub-steps:
1. If oil is burning in the engine, inspect the PCV (Positive Crankcase Ventilation) system for blockages or failures.
2. Replace the PCV valve if it's clogged or malfunctioning.
3. If compression is low, consider a complete engine inspection for piston rings or cylinder head issues.
4. Replace any worn engine components if necessary (e.g., piston rings, valves).

4. Final Checks

Sub-steps:
1. Refill the engine oil to the correct level using the manufacturer-recommended oil type.
2. Start the engine and allow it to idle while monitoring for leaks or burning smells.
3. Test drive the vehicle to ensure the issue is resolved.
