The PCV valve is located just to the right of the alternator...take off the 3800 cover (usually gray in color), and its behind the alternator and to the right of it, and you will see it popping out of the engine block right on the top of the engine case....its best to remove the alternator...u have to remove it to get to the pcv valve and replace it....

The PCV valve on a 1995 Buick Park Avenue is located on the top of the valve cover. Twist the valve and pull to remove and replace it.
