Throttle body ?

Has anyone heard of a problem with throttle body shafts leaking, I noticed that my twin 65mm bbk throttle body has air comming out around the shaft where the throttle cable connects too. Does anyone know of a fix for this or will I need a new throttle body, if so which one would be a good choice accufab? I do have a supercharger on my car, but only running 8lbs of boost so this should have not blown out a seal or anything. any ideas??
