After 3 years of chasing tiny metal shavings with a magnet, I finally bought a bore scope and found a cracked cylinder wall on a Cessna 172 that had been there the whole time.
That one little tool showed me a hidden crack that explained the weird oil consumption we'd been fighting for almost a year, and now I'm wondering what else I've been missing on routine inspections has anyone else had a bore scope reveal something obvious you'd overlooked?

Oh man that's rough, I feel for you. I mean three years of chasing oil consumption like that must have been so frustrating. Idk how you kept your cool that long. The thing that gets me is how something that small and hidden can cause such a big problem. I had a similar moment with a compression tester once, found a valve that was barely sealing and had been causing a rough idle for months. It's kind of wild how the right tool can just flip everything you thought you knew.
