## Discrepancy

ON CLIMBOUT OF KDTW THE CAPTAIN SAW SMOKE COMING FROM A VENT.  THIS WAS FOLLOWED BY A SMOKE TOILET CAUTION MESSAGE.  THE FLIGHT CREW COMPLIED WITH THE QRH, DECLARED AN EMERGENCY AND REQUESTED TO RETURN TO KDTW.  AN OTHERWISE UNEVENTFULL APPROACH AND LANDING WAS MADE AT KDTW.  AFTER CFR INSPECTION, THE AIRCRAFT WAS TAXIED TO THE GATE.  MAINTENANCE INSPECTED THE AIRCRAFT AND DISCOVERED A NUMBER ONE BEARING CARBON SEAL LEAKING ON THE RIGHT ENGINE.  THE CARBON SEAL WAS REPLACED AND THE COMPRESSOR WASHED.  HIGH POWER GROUND RUNS TO DRY OUT THE ENGINE PRODUCED NO SMOKE IN THE COCKPIT OR CABIN OR EVIDENCE OF FURTHER LEAKAGE.
