  Q: How to check and replace the PCV valve?

  A: The PCV valve is usually in the valve cover. To test it, have the engine idling, then remove the valve from the cover or intake manifold. Test for vacuum by covering the valve opening or hose. If there's no vacuum, replace any blocked or worn hoses. Check the valve by shaking it when the engine is off; if it doesn't rattle, replace it. Ensure the new valve is for your specific vehicle and engine size. Push the new valve into the hose end until seated. Check all hoses and grommets for damage and replace if needed, then secure the PCV valve and hose.
