What is the function and testing procedure of the PCV valve on 1989 Mazda 929?

PCV valves utilize intake manifold vacuum to avoid the leakage of crankcase blow-by gases. At idle the valve opens a little; as the engine speed increases it opens further. To test, heat the engine, disconnect and cover PCV hose - idle drop valve works. Install air cleaner, remove valve, put washers back, install.
