A. Check valve to prevent air flowing in and to allow air flowing out
B. Then the oil breather system isn't working as designed

As Aryan said, it is a crankcase vent valve. It only opens above a certain pressure threshold to allow crankcase pressure to flow into the intake. I was able to clean mine with some carburetor cleaner. I don't think it is available separate from the filler neck.
