How do I check and replace the PCV valve in my Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

If the engine runs at normal operating temperature, while idling, withdraw the valve (with attached hose) from the rubber grommet on the valve cover. In a V6 engine, PCV valve takes place in a valve cover. Take it out and see if there is any suction and shake it to check for rattles. Put your finger over the tip of the valve. If there is no vacuum at the valve, test a clogged hose, manifold port or valve itself. Replace any plugged or deteriorated hoses. Shut off engine and shake PCV valve; listen for rattle. If it does not rattle, get a new one to replace that which exists currently but doesn't make noise when shaken, and pull it out of end of hose so that you can take note its installed position as well as direction before replacing it again with an identical one To fit a replacement PCV vale, remove it from the end of hose and remember how it has been placed consequently you may have problems with finding appropriate vehicle model year, size for such an item purchased only after comparing previous characteristics with new ones Check for damage on rubber grommet and if need be install a new one. Lastly push another pcv valve and hose into their respective slots inside the valve cover securely.
