## Discrepancy

AFTER REACHING CRUISE ALTITUDE OF FL330 ENROUTE,  CAPTAIN OBSERVED RT ENGINE OIL PRESSURE FLUCTUATING FROM 42 TO 27 PSI.  FLT CREW PERFORMED QRH & REDUCED THRUST ON RT ENGINE.  JUST AS THE THRUST REDUCED, RT ENG LOW OIL PRESSURE MESSAGE ILLUMINATED FOR ABOUT 20 SECONDS & EXTINGUISHED.  FLT CREW NOTIFIED CENTER & REQUESTED A LOWER ALTITUDE.  FOLLOWING A DESCENT TO FL210, RT ENG OIL PRESSURE STILL FLUCTUATING.  FLT CREW ELECTED TO DIVERT.   A NORMAL APPROACH AND LANDING MADE.  DETAILED TROUBLESHOOTING WAS PERFORMED ON ENGINE.  BASED ON THE ENGINE'S HISTORY AS AN OIL CONSUMER & FAILURE OF NORMAL TROUBLESHOOTING PROCEDURES TO DETERMINE CAUSE OF PRESSURE FLUCTUATION, IT WAS DETERMINED TO REMOVE ENGINE.
