I did a run up a few weeks ago and found cylinder 2 with no EGT temp on one ignition.
I pulled the plugs a found oil had fouled the both plugs with more on the lower. The scope show normal valve but some glazing of the cylinder . Oil consumption was 1 per 10 hrs. I decided to change the cylinder with a new one. I did this with my mechanic.
I performed at 1 hrs test flight. I ran full throttle at 6000 feet about 80% hp. The #2 CHT was about same as the others at 350 degrees. The engine ran normally during the test flight.
I went to fly the next day. I did normal start and warm up with max ground leaning.
I did my run up and found cylinder 2 had a cold EGT again !
I have not pulled the plugs yet.
What do you think is happening? Next steps ?
Thanks
