Found a kids toy fire truck once.

That Model 10 cylinder gap is a perfect example. You can get a 0.006 feeler in there, but is it dragging or just kissing? Pin gauges remove the arm strength variable. I set my K-frame at 0.005 and it's the same reading every single time, no guesswork. It turned a frustrating process into a thirty second check.

The no-clean stuff wipes right off with some IPA.

Ever notice how the trip meter seems to sync up with weird odometer readings? I started resetting mine at fill-ups to track mileage, and now I catch patterns all the time. Last month it was 123,456 miles with 100.0 on the trip, felt like a slot machine payout.

My buddy had that happen on a hike. Said the quiet was so thick it felt like the world had paused. Kinda freaked him out.
