Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil catch pan, compression tester.
Ensure the vehicle is parked on a level surface and the engine is cooled down. Disconnect the battery before starting any disassembly.

2. Replace Oil and Filter

Drain the old oil:
1. Position the oil catch pan beneath the engine.
2. Remove the oil drain plug using a socket set and allow the oil to fully drain.
Replace the oil filter:
1. Locate the oil filter and use an oil filter wrench to remove it.
2. Lubricate the rubber gasket of the new oil filter with fresh oil and install it hand-tight.
Refill with new oil:
1. Replace the drain plug and tighten it to the manufacturer’s torque specification (typically around 25-30 Nm).
2. Use the recommended oil type (e.g., 5W-30 synthetic) and refill through the oil filler cap.

3. Inspect and Replace PCV Valve

Locate the PCV valve:
1. Remove any covers or hoses obstructing access to the PCV valve.
Inspect the valve:
1. Remove the PCV valve and check for clogs or damage.
2. Clean or replace the valve as necessary.
Reinstall the PCV valve securely, ensuring all hoses are connected properly.

4. Address Internal Engine Components

If excessive oil consumption persists:
1. Perform a compression test to check cylinder health.
2. If low compression is detected, consider replacing piston rings or valve seals.
3. This may involve a complete engine teardown; consult service manual for specific procedures.
