I completed a flight yesterday and noted that I had what appeared to be a partially blocked injector on my #2 due to a significant increase in EGT to all other cylinders on approach back into my home airfield.
As such, today I completed a full injector clean and inspection.
While I was completing a bore-scope inspection I noticed what appeared to be a crack in one of the valve seats in the cylinder. I don't see any issues with the actual valve and it could well be some lead deposit and light creating the illusion of an issue, however, thought it best to post some images and get comments as what people believe the image contains and what options would then be required to pursue.
Valve top and edges look good.
Apparent crack.... and interesting section with a bit of oil in it.... uhhmmm... don't know.....
Closer look at the edge of the valve and the seat. Some lead deposited on entry to lip.
Any thoughts and experience is greatly appreciated as I would not want to have this progress further if an issue.
