Recently purchased RV-6A, and my first task is getting oil temperatures under control. Cruising probably 85 deg at 3500, the engine needed to be managed diligently to avoid redlining oil temp. I'll be sure to get more exact conditions and power settings next time out. Engine is an IO-320-C1A with piston squirters (which I understand contributes to the high oil temp), but I've found advice that indicates the standard oil cooler should still be sufficient. Oil cooler is mounted on the firewall. Ducting to the oil cooler strikes me as a possible trouble spot with that big bend in the scat tube. I also have read that openly venting the oil cooler into the lower cowl reduces the pressure differential between the air inlet and outlet. Am I on the right track here? Any suggestions of things to do or check? Or should I just spring for the bigger cooler?
