## Discrepancy

LEFT ENGINE ENGINE OIL TEMPERATURE INDICATION HIGH TEMPERATURE - #1 OIL TEMPERATURE FLUCTUATION. DURING CLIMB (PASSING 35,000?) WITH THROTTLE IN CLIMB DETENT, #1 OIL TEMPERATURE FLUCTUATION FROM NORMAL TO MAXIMUM REDLINE. ON LEVEL OFF AND IN CRUISE POWER, #1 OIL TEMPERATURE SETTLES AT 100C AND INTERMITTENTLY FLUCTUATES +- 20C THROUGHOUT THE FLIGHT. #2 OIL TEMPERATURE STEAD AT 80C ALL FLIGHT. NO ABNORMAL SECONDARY INDICATIONS NOTED. *** CORRECTIVE ACTION *** INSPECTED TEMP BULB INSTALLATION AND NO ABNORMAL CONDITION NOTED. RAN L/H ENGINE AND MONITORED TEMP INDICATION AND IT APPEARS TO BE GOOD. CONNECTED P&W ENGINE DOWNLOAD CABLE AND ATTEMPTED TO DOWNLOAD DCU BUT NO COMMUNICATIONS. TRIED MULTIPLE TIMES AND WE WERE ABLE TO DOWNLOAD THE DCU FILE, SENT TO MCC AND P&W FOR REVIEW. REMOVED AND REPLACED OIL TEMP SENSOR, OPS AND LEAK CHECK PASS.
