    Q:
    How to check and replace the PCV Valve on Chevrolet Beretta? Posted by Jarek T.
    A:
    Start the engine and then stop it. Pull the valve (with hose attached) out of the rubber grommet in either the rocker arm cover or camshaft cover. Put your finger over the end of the valve. Check for a plugged hose, manifold port, or valve itself if there is no vacuum at the valve. Change any plugged or deteriorated hoses' Turn off the engine and shake PCV valve listening for rattle. Fit new one if valve doesn't rattle. To put a new VALVE on pull it out of the end of hose with attention to where and how it was installed. Whenever purchasing a replacement PCV valve, make certain that you are getting one that is designed for your particular vehicle, model year and engine size. Ensure they are similar by comparing old valve with new one. Push in the valve until seated into end of hose. Replace grommet if damaged; inspect rubber grommet for damage and replace as necessary. Push firmly into place PCV valve and hose into rocker arm cover or camshaft cover.
