- If leaks are found, replace any damaged gaskets or seals (e.g., valve cover gasket, oil pan gasket).
- Use a gasket scraper to remove old gasket material.
- Apply a new gasket and follow torque specifications.
- Torque values may vary; refer to the service manual for specific values.

3. Oil Change

Drain Old Oil:
- Remove the oil drain plug and let the old oil drain into a pan.
- Tools Required: Socket set, oil catch pan.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Lubricate the rubber gasket of the new filter with new oil and install it.
Add New Oil:
- Replace the drain plug and refill the engine with the manufacturer's recommended oil.
- Tools Required: Funnel, oil.
- Ensure the oil level is within the acceptable range on the dipstick.

4. Check PCV System

Inspect PCV Valve:
- Remove and inspect the PCV valve for blockages or wear.
- Clean or replace the PCV valve if necessary.
