I'd like input from those with experience.
Lycoming IO-540 D4A5 in my RV-10. 315 tach hours since new.
Compressions fine all >70/80 cold. Runs fine no issues. I run LOP when on XC flights but otherwise ROP. CHTs generally well less than 400, though they will approach 400 on takeoff on a hot day.
I'm interested to see what people think of the borescope pics from annual this year (taken today). They are presented in order, cyl 1 to 6:
The only one that looks odd to me is #1, but I am not sure what to make of it.
Thanks in advance for any input.
