I have a 1976 Cessna 182P, has 150 hours on rebuild engine with new Millenium cylinder assemblies. I recently installed at 6 probe digital CHT gauge which seems to work perfectly. The interesting thing I have only just noticed is that when in cruise with cowl flaps closed or nearly closed, the CHT's can drop as much as 40 degrees when the cabin heater is cracked open about an inch or so. Close the cabin heater and the temps go back up. The aircraft standard CHT does not seem to move but perhaps it is not sensitive enough. Does anyone have any ideas on this, or has anyone else noticed this? Is it because the cabin heat allows a bit more air circulation through the cowling? I would appreciate any input. Ted
