I have an RV-9A with ECI/Penn Yan Aero 0-320-D1A engine (160 HP). I also have the Hartzell constant speed prop purchased through Van's. The oil cooler is the standard unit purchased in the Van's firewall forward kit. Hot summer days find me with oil temps in the 200-220 range on climbs at 120-130 MPH. The cooler is mounted behind the #4 cylinder per the plans.
Anyone out there having similar problems? Any ideas about the possibility of clogged cooling tubes, etc? Testing for same?
The total time on engine and airframe is just over 238 hours since first flight on June 9, 2005. The typical oil temp is around 180 degrees F when cruising up high (7,500 to 12,500 MSL) at 160MPH TAS.
