Where is the PCV valve located on a 1997 Ford Ranger 2.3 liter engine?

On a 1997 Ford Ranger 2.3L engine, the PCV valve is typically located on the valve cover. It's usually a small, plastic or metal valve with a hose connected to it. It's often near the rear (firewall side) of the valve cover, but its exact position can vary slightly depending on the specific engine configuration. You'll need to visually inspect the valve cover to locate it. Look for a small, capped valve with a hose running to the intake manifold.
