## Discrepancy

(CAN) THE PILOT REPORTED THAT THE LT FUEL INLET TEMPERATURE WAS IN THE RED. TURNING ON THE AUX FUEL PUMP IAW THE QRH LOWERED THE TEMPERATURE. THE HIGHEST TEMPERATURE OBSERVED WAS 74 DEGREES.  MAINTENANCE PROCEEDED TO REPLACE THE LT FUEL HEATER TEMPERATURE CONTROL VALVE.  WHEN THE VALVE WAS REMOVED OBSERVED OIL ON THE FUEL SIDE OF THE VALVE AND ELECTED TO REPLACE THE ENTIRE FUEL HEATER ASSEMBLY.
