The oil port on a Campy hub is just that-an oil port. In days of yore racers used oil, not grease and it could be renewed every day though the port. The only hub I know of that used a port to force grease through the hub is the slightly OT WildernessTrail/Suntour Grease Guard hub. Remember that grease is simply oil held in a soap so that is doesn't run out of the bearing. Phil Brown Has a grease Guard BB in Berkeley, Calif.
