- Allow oil to fully drain.
Replace the oil filter:
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new oil filter, hand-tightening it securely.
Reinstall the drain plug and tighten to manufacturer specifications (usually around 25 Nm).
Refill engine with the recommended oil type (check owner's manual for specifications).

4. Replacing PCV Valve
