Where is the PCV valve located on a 2001 Chevy S-10 pickup?

The PCV valve on a 2001 Chevy S-10 is typically located on the valve cover. It's a small, usually black, plastic or metal valve. However, the exact position on the valve cover can vary slightly depending on the engine (4.3L V6 or 2.2L 4-cylinder). It's often near the back of the valve cover, but you'll need to visually inspect your valve cover to locate it. Look for a small hose connected to it, which is part of the PCV system.
