Claim:
A valve for crankcase ventilation of an internal combustion engine, said valve comprising a fresh-air side for connection with an intake section of the internal combustion engine, an engine side for connection with the crankcase and a valve insert movable as a whole for changing the flow resistance through the valve, wherein said valve insert is held inside said valve without pre-load, wherein said valve insert is designed to be freely displaced to a deventilation limit-stop position at which deventilation occurs under negative pressure on the fresh-air side relative to the engine side, and to be freely displaced to a ventilation limit-stop position at which ventilation occurs under excess pressure on the fresh-air side relative to the engine side, wherein the valve insert is designed to open a deventilation cross-section in the deventilation limit-stop position and to open a ventilation cross-section that is different from the deventilation cross-section in the ventilation limit-stop position.
