Subarus do have PCV valves. The PCV valve in a Subaru is responsible for regulating the flow of gases from the crankcase back through the intake manifold to the cylinders, rather than allowing them to escape into the atmosphere. A clogged PCV valve can cause increased oil consumption and other engine problems . It is recommended to replace the PCV valve as part of regular maintenance, typically around every 30,000 miles.
