## Discrepancy

ON TAKEOFF, CREW NOTED THE LEFT ENGINE OIL TEMPERATURE WAS HIGH (165 DEGREES C).  THE TEMPERATURE DIMINISHED WHEN THE POWER WAS DECREASED.  CREW ALSO NOTED A LIGHT SMOKE/OIL SMELL IN THE COCKPIT.  THE FLIGHT RETURNED TO AIRPORT.  UPON ARRIVAL, FUEL AND OIL WERE OBSERVED DRIPPING FROM THE LEFT ENGINE.  MAINTENANCE REPLACED THE FUEL COOLED OIL COOLER.
