Solution

1. Preparation

Gather tools: OBD-II scanner, compression tester, socket set, torque wrench, oil catch pan, and rags.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Replace PCV Valve

Locate the PCV valve: Refer to the service manual for the exact location.
Remove the PCV valve: Detach any hoses connected to the PCV valve.
Inspect the valve: Shake the valve; it should rattle. If it doesn't, replace it.
Install new PCV valve: Connect the new valve securely and reattach hoses.

3. Conduct Compression Test

Remove spark plugs: Use a spark plug socket to carefully take out the spark plugs.
Insert compression tester: Screw the tester into the spark plug hole of the first cylinder.
Crank the engine: Have someone crank the engine while you monitor the compression reading.
Record results: Repeat for all cylinders and compare readings. Low compression indicates potential issues.

4. Inspect Turbocharger (if applicable)

Remove intake and exhaust ducts: Use the socket set to detach any ducts connected to the turbo.
Check for oil leaks: Inspect the turbine seals and housing for oil presence.
Replace seals if necessary: If leaks are found, replace the oil seals according to specifications.
