That small tube is a vent for the flywheel cavaty. There are a set of shaft seals on the driveshaft that prevent water from leaking into that cavity. If you see any water vent from that tube, you have a seal failure that is described in a service bullitit from Honda. If the water accumallation is not fixed, the water will rust out the starter motor.
