Hello,
New to the forum, asking for opinion on what we uncovered during my recent annual. I attached a photo so hopefully it is visible and it clear enough for everyone to see. The plane is a 1969 Cherokee 140 O-320 E2A. Basically, the section of exhaust under the shroud which sends warm air to the carb appears to be twisted and/or deformed. It has been several years since the shroud was removed but I never remember it looking like this. The slip joint was frozen so we dropped the two sections together and replaced. But the mechanic (who is new to the plane) has never seen anything like this. He said I appear to be leaning correctly based on how the plugs looked but I'm not sure if that would be conclusive on something like this. To me, it looks like it was hot, but why only under the shroud? The rest of the pipe appears fine, exhaust inspection was good as well. Any one out there have ideas?
