Where is PCV located on a 1996 Chevrolet Blazer?

The PCV (Positive Crankcase Ventilation) valve on a 1996 Chevrolet Blazer is typically located on the valve cover. However, the exact location on the valve cover can vary slightly depending on the engine (4.3L V6 or 5.7L V8).

To find it, look for a small, usually plastic valve with a hose connected to it. One hose will go to the intake manifold, and the other will be connected to the valve cover itself. It's often a dark-colored plastic piece.

Because there's some minor variation depending on engine type and even minor model differences within the 1996 Blazer lineup, it's best to consult a repair manual specific to your Blazer's engine for a precise diagram. A quick online search for "1996 Chevrolet Blazer [your engine size] PCV valve location" with images should also help you pinpoint it visually.
