## Discrepancy

BOS - CONTAMINATED AIR IN COCKPIT AND CABIN.  THE ODOR SMELLS LIKE CONTAMINATED OIL; WITH PACK 2 OFF AND FRESH AIR THE ODOR IS GONE.  MAINTENANCE REMOVED AND REPLACED THE RIGHT PACK AIR CYCLE MACHINE AND THE RIGHT PACK HEAT EXCHANGER.  ALL LEAK AND OPERATIONAL CHECKS ARE SATISFACTORY.
