## Discrepancy

OIL PRESSURE INDICATING SYSTEM OIL PRESSURE (01=L ENG, 02=R ENG) READS PSI WITH ENGINE SHUT DOWN ENG 2 OIL HIGH PRESSURE IN CRUISE. OIL PRESSURE DIFFERENCE OF 20 PSI BETWEEN ENG 1 AN ENG 2 IN CRUISE AND DROPPED TO A 10-PSI DIFFERENCE DURING DESCENT.RMK PICTURE TAKEN DURING DESCENT AT CRUISE FLIGHT RIGHT ENGINE OIL INDICATED 20 PSI HIGHER THAN THE LEFT ENGINE, ON DESCENT THE OIL PRESSURE HAD DROP TO 10 PERCENT DIFFERENCE RIGHT ENGINE STILL HIGHER.  REMOVED AND REPLACED NR 2 ENG OIL PRESSURE TRANSMITTER IAW TASK 79-32-01-424-009-R00, LEAK CHKD GOOD, PRESSURE INDICATING NORMALLY ON THE GROUND.
