That vent hose is conneted to the crankcase breather on the side of the engine,There are 2 screws holding the breather in place.
Remove the breather and turn it up,There is a hole with a brown disc inside.
Take your finger and lightly tap on the brown disc it should have a springy feel to it (it wont move much) so look closely,If it doesn't spring back up that could very well be your problem. Replace it with a new one.
