Does anyone know if there is an offset/curved/canted spacer to go between the oil cooler and the opening on the number 4 baffle on an IO360 parallel valve RV8. I have the large oil cooler and have also done all of the checks (oil flow, crimped oil line, vernatherm,etc) to make sure that my problem is not airflow. I have flown the airplane for 369 hours and I constantly struggle with marginally high oil temperatures. I'd like to get this problem squared away before the summer flying season gets started. Can anybody provide a drawing or better yet tell me where I can find one already built?
