Where is the location of PCV on a 1999 Subaru Legacy sedan?

The PCV (Positive Crankcase Ventilation) valve on a 1999 Subaru Legacy sedan can be found on the driver's side of the engine bay. It is usually located near the top of the engine, close to the valve cover. The PCV valve is a small, cylindrical-shaped device with a hose connected to it. It helps to regulate the flow of air into and out of the crankcase, which helps to keep the engine running smoothly.
