High CHT on O-540
I just purchased a 1979 Piper Dakota. I just had the engine overhauled and have about 30 hours on a overhauled O-540. The CHT on Cylinder #2 and #3 exceed 425 degrees on climb out but settle in at 400 - 410 degrees. All other cylinders are fine. In the Lycoming O-540 manual it says that 435 degrees on high cruise is not to be exceeded. Talking with several A&P's they all express concern about the high CHT's. I have had the baffling completely redone as well as the timing checked. Any ideas why my CHT's might be high or is this normal for the O-540?
