1973 Challenger. I have been seeing relatively high CHT's on #3 and 4 cylinders. Breaking slightly above 400 on climb and staying in the 380 range during level flight. Lean or rich doesn't seem to have a big effect. The baffles seem to seal reasonably well against the cowl and I put some RTV in any holes I could find with a shop light to limited effect.
The one thing I wonder about is the plane originally had Air Conditioning, which has been removed. The passenger side front baffle has a large cut-out where I assume the compressor used to be. Could that be preventing full pressure to drive air through the cylinders?
I'm getting slightly elevated iron on oil analysis and Blackstone seems to think that the elevated CHT might be contributing.
