In a 2008 Subaru Outback, the PCV (Positive Crankcase Ventilation) valve is located on the driver's side of the engine, typically on the valve cover. It is often found near the rear of the engine, connected to a hose that leads to the intake manifold. To access it, you may need to remove some engine covers or components for better visibility. Always consult the owner's manual or a repair guide for specific instructions related to your vehicle.
