Another question for you fine experienced Enstrom folk. 1977 280C. I am finding as the temperatures increase around here if I fly slow for surveillance or other need to slow down I find my oil temperature increasing. It isn't going beyond max, but my JPI screams at me, starts flashing, starting at about 230. Once I speed up it starts decreasing, but I'm concerned with thermal runaway or something. Is it because I may be leaning too agressively, 1530-1570 TIT, or just because I'm not getting enough fresh air through the intake? What is your experience and do you have any recommendations? I see in the logs they removed a secondary oil cooler. I wonder if that is a solution to reinstall it. If not I guess I have to limit my low and slow or slow orbits.
