    Q:
    How can I check if the PCV Valve is functioning properly for the 1995 Chevrolet Blazer? Posted by Tiernan W.
    A:
    To check it, pull it out and feel for suction and shake it to make sure it rattles. Place your finger over the end of the valve. If there is no vacuum at the valve, check for a plugged hose, manifold port, or the valve itself. You can Select Your Vehicle to see complete installation and repair tips.
