## Discrepancy

DIRTY SOCK ODOR ON DECENT OUT OF 12000 THRU LANDING. USED OXYGEN MASK UNTIL JUST PRIOR TO LANDING. NO ODOR NOTED ON TAXI IN. #2 ENGINE DETERMINED TO BE SOURCE OF ODOR DUE TO EVIDENCE OF OIL IN FAN HUB. AIRCRAFT WAS GROUNDED. REMOVED LPT VENT SHAFT,  REPLACED O-RINGS ON SHAFT RE-INSTALLED LPT VENT SHAFT. RAN #2 ENGINE AT 75% N1 FOR 15 MIN, NO OIL FOUND IN HUB. OK FOR SERVICE.
