Here is today's puzzle: CHT #6 fluctuates in cruise intermittently.
This is the second time and both times was on a hot day. There is hardly any change in EGT. There is one EGT spike for EGT#6 at 1:38:42. No sign of a major exhaust leak. Baffles look fine (one year old),
The flight was at 2430 RPM, WOT, 12500 feet, 50-70 ROP, 14.6 GPH fuel flow and take off was from KHND at 100 deg f, 130+ kts cruise climb at the lower part of the blue bar (EGT).
What could cause this?
