## Discrepancy

AFTER LANDING AND JUST AFTER STOWING THE THRUST REVERSERS, THE CREW NOTED THE LOW OIL PRESSURE WARNING LIGHT ON AND EGT INDICATION ABOVE REDLINE FOR THE NR 4 ENGINE.  THE ENGINE WAS SHUT DOWN AFTER REACHING A MAX EGT OF 1132C FOR 73 SECONDS.  MAINTENANCE REPLACED THE ENGINE FOR OVERTEMP.  EXACT PART CAUSING THE COMPRESSOR STALL TO BE DETERMINED.
