## Discrepancy

DURING CRUISE, A MIST WAS NOTED COMING FROM THE UNDERSIDE OF THE NR 1 ENGINE.  THE AIRCRAFT RETURNED TO NRT.  THE ENGINE WAS SHUT DOWN 15 MINUTES BEFORE LANDING.  NO FUEL WAS DUMPED.  THE GEARBOX SCAVENGE PUMP WAS REPLACED AND A RUN-UP SHOWED NO EVIDENCE OF ANY LEAKAGE.  THE AIRCRAFT WAS POSITION FERRIED TO KIX AND AGAIN EXPERIENCED THE MIST.  THE AIRCRAFT WAS FERRIED BACK TO NRT WHERE THE ENGINE WAS REPLACED.
