Borescope vs. my old flashlight trick, not even close after yesterday's inspection
I spent 15 years using a flashlight and a mirror to check cylinder walls on radial engines. Yesterday I borrowed a cheap borescope from the shop next door at KVNY and spotted scoring in a #4 cylinder that I would have completely missed. Has anyone else switched over and found hidden damage on engines they'd already signed off?

Damn, borescopes make you feel like a damn detective!
