What was found
RIGHT ENGINE OIL TEMPERATURE INDICATION WENT TO RED LINE WHEN IN CRUISE CONFIGURATION. WHEN POWER WAS REDUCED, OIL TEMPERATURE WENT INTO THE GREEN. THE OIL TEMPERATURE REGULATOR/PRESSURE RELIEF VALVE IS SUSPECTED TO BE STICKING AS THE INSTALLATION OF A NEW REGULATOR CURES THE PROBLEM. NOTE: THE EXACT SAME PROBLEM OCCURRED ON THIS AIRCRAFT, ON THE LEFT POSITION, ON 12/06/2001 AT 110.7 HOURS, AIRCRAFT AND PART TOTAL TIME.
