## Discrepancy

SCAN OF GAUGES AT PRE-TAKEOFF CHECK SHOWED ALL ENGINE PARAMETERS IN THE NORMAL RANGE. A FEW MILES FROM THE AIRPORT (ABOUT 9 MINUTES FROM LIFT) I NOTICED #2 ENGINE OIL TEMP HAD EXCEEDED THE LIMIT AND REACHED 145C. I SLOWED THE AIRCRAFT , BROUGHT ENGINE #2 TO IDLE, AND TURNED BACK TO OUR BASE. ENGINE OIL TEMP REDUCED TO NORMAL RANGE UNDER THIS FLIGHT CONDITION. WE NOTIFIED EL CENTRO APPROACH OF THE SITUATION WITH OUR ENGINE AND ALSO INFORMED AIR COMM. ON APPROACH I RETURNED ENGINE #2 TO FLIGHT CONDITION AND LANDED NORMALLY WITH BOTH ENGINES FULL POWER.  ONCE ON GROUND ATC WAS NOTIFIED LANDING ASSURED. NO EMERGENCY CREWS WERE DISPATCHED. I THEN CALLED MAINTENANCE, OCC, AND THE AOC.
