This is a small heater to free up any frozen water vapours that may be
in the recirculating crankcase fumes and could block the tube.  But it
is ironic that the main blockage that occurs is not from ice but the
collapse of the tube itself through rotting.  New tubes can be
purchased from places like Volkscafe for about $6.
