Oil Temp dropping to - 20 Deg C
I took a long flight last week, could not get the oil temp up to 50 Deg C. I was around -20 to 10 Deg C. Oil pressure perfect. It seemed to get worse longer into the flight 1 Hour in to a 3 Hour flight.
I checked all the wiring from the sensor pick up to the IEFIS control box all perfect. I took a flight this morning remained in the circuit 20 Min. it was perfect on start up waited to 50 Deg before take off stayed between 30 Deg to 60 Deg. Outside temp around 7 Deg.
Should I replace the sensor?
