Solution

1. Preparation

Gather tools: socket set, torque wrench, oil catch pan, and rags.
Ensure the engine is cool and the vehicle is parked on a flat surface.

2. Address Oil Leaks

Identify Leak Source:
- Clean the area around suspected leak points with engine cleaner.
- Start the engine and observe for fresh oil leaks.
Replace Gaskets or Seals:
- If the valve cover gasket is leaking, remove the valve cover by loosening bolts (typically torqued to 8-12 Nm) and replace the gasket.
- If the oil pan gasket is leaking, drain the oil and remove the oil pan. Replace the gasket and reassemble.

3. Change Oil and Filter

Drain the engine oil into an oil catch pan and replace it with fresh oil (consult the owner’s manual for the correct type and quantity).
Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated with oil before installation.

4. Inspect and Clean

Inspect the exhaust manifold and catalytic converter for burned oil residue. Clean any residue using appropriate cleaning solutions.

5. Check PCV System

If the PCV valve is clogged, replace it to ensure proper crankcase ventilation.
