I know I should know this, and searching the forums didn't find me an immediate answer...
What are the possible reasons for a cylinder running hot (CHT) on an IO550?
What I can tell you is that it is the hottest both LOP and ROP (so it isn't a clogged injector?) meaning I have to go either extra lean or rich to keep that cylinder from getting out of my sub 400 degree comfort zone in cruise. This just started - coincidentally after an oil change.
It also seems to have the lowest EGT of all the cylinders...
Where should I start?
thanks!
