Question for our engines expert: I have an RV-6 with a Lycoming O-360 and in winter, even with the louvres of the oil cooler closed, my oil temperature may only reach about 150°-160°. Can I install a shut-off valve to prevent oil flow through the cooler in cold weather, or does oil need to flow through it to keep oil pressure from getting too high?
