Solution

1. Preparation

Gather tools: OBD-II scanner, oil filter wrench, oil catch pan, rags, and appropriate replacement oil.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Change Oil and Filter

Drain Old Oil:
- Remove the oil drain plug with a socket wrench and allow the old oil to fully drain into the catch pan.
- Replace the drain plug and tighten to the manufacturer’s specified torque value.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Prepare the new oil filter by applying a small amount of new oil to the rubber gasket on the new filter.
- Install the new oil filter, hand-tightening it securely.
Add New Oil:
- Using a funnel, pour the recommended type and amount of new oil into the engine.
- Start the vehicle and let it run for a few minutes, checking for leaks.

3. Inspect and Repair PCV System

Access the PCV Valve:
- Locate the PCV valve in the engine compartment (refer to the service manual for exact location).
Remove and Inspect:
- Detach the PCV valve from the engine.
- Check for blockages or damage to the valve.
Replace if Necessary:
- If the valve is faulty, replace it with a new one.
