Do you have any pictures of what a clean efficient oil cooler set up looks like?

Todd,

Focus on the air entering and leaving the cooler. Exit blockage or back pressure could inhibit cooling. High speed air hitting the entry fins can form Pressure fronts and inhibit air from entering cooler.

Stumped. No ideas from IA or even Continental Engines support either. Last year I had to do lower power climb and step to keep it within limits. I bought the plane last July with about 650 TT. Only about 20 hrs then since overhaul. By John Jewel. He had no ideas beyond what I had done either. Compressions and Borescope looked good. No glazing, no oil blowby that could be detected. And no consumption problems.
