## Discrepancy

NORMAL FLIGHT UNTIL CLIMBING THROUGH FL300, NOTICED OIL PRESSURE FOR NR 2 ENGINE WAS IN THE AMBER RANGE ON THE EICAS.  CHECKED QUANTITY OF OIL ON NR 2 ENGINE, NOTICED ONLY 3 QUARTS (8 QUARTS OBSERVED DURING AFTER START CHECK).  PRESSURE FELL TO 19 PSI IN THE RED RANGE & MASTER CAUTION BELL WENT OFF ALONG WITH ASSOCIATED EICAS WARNING FOR LOW OIL PRESSURE.  RAN QRH, ADVISED TO DO A PRECUATIONARY ENGINE SHUTDOWN.  TOTAL TIME FROM NOTICING OIL PRESSURE & TIME ENGINE SHUTDOWN APPROX 3 MINS.  NO OTHER ENGINE LIMITS EXCEEDED.  ATC CLEARED DIRECT TO CMH.  REST OF FLIGHT WAS UNEVENTFUL, LANDED OVERWEIGHT.  REMOVED & REPLACED MAGNETIC CARBON SEAL FOR NR 2 GENERATOR & NR 2 FPMU.  RAN ENG, CHECKED FOR LEAKS, NONE FOUND.
