## Discrepancy

DURING INITIAL CLIMB, THE CREW NOTICED THE RT ENGINE OIL PRESSURE GUAGE HAD DROPPED TO ZERO PSI AND IT WAS NOT ASSOCIATED WITH A RT OIL PRESS ANNUNCIATOR.  20 SECONDS LATER THE CREW NOTICED A HARD BY-PASS AT ROUGHLY 630 DEGREES EGT.   CREW INFORMED TOWER AND RETURNED BACK TO DEPARTURE WITHOUT INCIDENT.  R & R THE RT ENGINE OIL PRESSURE TRANSDUCER IAW THE MM 79-30-01.  GROUND RUN AND OPS CHECKS GOOD.
