The difference 6 months of using a bore scope made on my engine inspections
I started using a bore scope on every annual inspection about 6 months ago after a guy at a hangar in Tulsa showed me what he found on a Lycoming. Before that I was just doing the usual visual checks and hoping nothing was hiding. The first time I looked inside a cylinder that looked perfect on the outside I found scoring that was bad enough to ground the plane. Now I catch stuff like pitting and carbon buildup way earlier and it saves the owners a ton of money on major overhauls. I even found a cracked exhaust valve guide on a 172 that nobody would have seen without the camera. Has anyone else had a weird finding pop up on a borescope that you would have missed otherwise?

You ever pull a cylinder that looked fine from the outside but had a hairline crack hiding right where the barrel meets the head? Found that on a 182 last year. Would've totally missed it without the scope since there was no oil or compression loss yet.

Three 172s I inspected last month had the same hidden crack in the same spot...
