Where is the PCV valve located on a 2003 impala 3.8 liter engine?

On a 2003 Chevrolet Impala with a 3.8L engine, the PCV valve is typically located on the valve cover, near the rear (firewall side) of the engine. It's often a small, usually plastic, valve with a hose connected to it. However, the exact location can vary slightly depending on specific engine variations. It's best to consult a repair manual specific to your vehicle's year and engine to be absolutely certain. A visual inspection with the engine bay clean will greatly assist in locating it.
