For those of you who have flown your RV-14 through the winter, have you had any issues with oil temps running too cool? On my RV-8A (O-360) I had a cockpit-controlled butterfly valve in the opening of the baffles that fed the 4" SCAT tube running to the cooler, and I could close it off on cold winter days to help bring the oil temp up more quickly and maintain at least 180 F when the OAT was way down in the single digits (Fahrenheit). The IO-390 angle valve engine expels a greater amount of heat through the oil cooler, so I'm wondering if a door to control airflow in winter may not be as beneficial as it was on the parallel valve O-360. Any thoughts?
