Looking for advice for this problem.  Oil cooler door may help a little but the trade off of oil temp increase vs CHT increase is a trap at high power climb and in slow flight.  Two hours of flight time and problem is consistent up to about 8,000 or 9,000 ft.  One idea suggested is to fair the inside top of the intake cowl on the left side because turbulence here will decrease the airflow to the top left side of the engine.  One person indicated he did this with a IVP and achieved a 20 degree drop in EGT by doing this. 

 

Anyone else have experience with that?

 

Thanks in advance and to those who have sent congratulatory emails.
