Narrative:
Passing FL270 flight engineer advised me #3 oil temperature gauge had failed. At that moment #3 fuel heat valve light illuminated without activating the switch. No way to measure oil temperature. After following all procedures and abnormals for both problems, we found that operating the engine below 1.65 EPR that fuel heat valve light remained out. After talking to air carrier technician 30 mi from iah, both myself and crew and air carrier technician deemed a safe operation to continue to destination. All operations were normal from iah to dfw and landing was uneventful. Both items were entered in logbook. Trip completed and only slightly late due to reduced cruise speed for reduced thrust operation.

Narrative: PASSING FL270 FE ADVISED ME #3 OIL TEMP GAUGE HAD FAILED. AT THAT MOMENT #3 FUEL HEAT VALVE LIGHT ILLUMINATED WITHOUT ACTIVATING THE SWITCH. NO WAY TO MEASURE OIL TEMP. AFTER FOLLOWING ALL PROCS AND ABNORMALS FOR BOTH PROBS, WE FOUND THAT OPERATING THE ENG BELOW 1.65 EPR THAT FUEL HEAT VALVE LIGHT REMAINED OUT. AFTER TALKING TO ACR TECHNICIAN 30 MI FROM IAH, BOTH MYSELF AND CREW AND ACR TECHNICIAN DEEMED A SAFE OP TO CONTINUE TO DEST. ALL OPS WERE NORMAL FROM IAH TO DFW AND LNDG WAS UNEVENTFUL. BOTH ITEMS WERE ENTERED IN LOGBOOK. TRIP COMPLETED AND ONLY SLIGHTLY LATE DUE TO REDUCED CRUISE SPD FOR REDUCED THRUST OP.
