However the oil temperature is quite high. It's between 205-225F. I use a IO360A1B6 with the normal Vans cowling and a Positech cooler with external entry. Any ideas?? Thank you -- Stephan J.W.

The problem is with the Positech oil cooler. They do not have near the cooling capacity of aircraft oil coolers. Remove it and replace it with a 9 or 10 row Niagara oil cooler and mount it behind and slightly above cylinder number 4 on the rear baffle. Tilt it back and down 25 1/2 degrees (maximum tilt without rubbing the engine mount). This will give you maximum cooling and has worked well in all temperature ranges up to 100 degrees air temperatures and more with the IO360AlB6 engine. Niagara coolers can be purchased out of Trade A Plane. They are usually discounted to approximately $300.00. Be sure and install with long bolts through both flanges of the oil cooler with tube spacers between the flanges (otherwise cooler flanges will crack). Good luck. Where is Bockhorn? I may travel to England this fall for bird hunting and my english friend has a airplane. It would be fun to fly over for a lunch and visit. Auf Wiedersehn, Dick Martin RV8 N233M the fast one > >
