I recently completed my CI and did a test flight today. Everything seemed all normal at first. As I climbed out of the pattern and into 3000 I quickly noticed engine roughness. Then looking at the engine gauges I saw number 2 cylinder CHT rising through 400 and the EGT dropping to about 1000. I quickly reduce power and headed back to the airport. Upon descending to about 2000 ft the temps came back to almost normal (although #2 egt was about 100 degrees less than the others which isn't normal). I landed pulled the cowl and visually inspected everything. Saw no visible issues so I put the cowl back on and tookoff. I stayed above the airport. And again upon climbing to 3000 ft egt dropped and cht rose... Landed again.
The only thing I did during the CI was change the intake gasket. Thinking that was a good idea for some reason. I only had 2 gaskets on me, so I changed number 2 and 4 intake gaskets. (before I ordered more gaskets someone told there is no need to proactively replace these gaskets, so I did not change 1 and 3)
My thinking is I have an intake leak most likely from the gasket. Is my thinking correct here.? Climbing in altitude is causing more air to leak and thus lean out the cylinder... ??
thanks for the help.
