That old mechanic in Atlanta saved me 3 hours of chasing a leak by teaching me to soap test every fitting twice
I was ready to pull my hair out over a slow hydraulic drip on a 737 pack valve for 2 days, then this guy at the hangar showed me to soap it, wait 90 seconds, then soap it again and that second pass caught a tiny micro-crack I'd missed every time; has anyone else found a weird timing trick like that for pressure checks?

Same here man, I used to hate double-checking stuff but that trick actually proved me wrong lol.

Exactly. The real mindfuck is when you start double checking the things you're totally sure about. @ray_sullivan caught that part. I caught my doctor making a prescription error once because I verified a dosage I "knew" was right. Almost took the wrong amount if I hadn't checked.

Man that's the whole secret right there. The stuff you're dead sure about is usually where the gremlins hide. I had a similar thing with my pressure washer's unloader valve once, thought I knew exactly what was wrong because I'd fixed the same model a dozen times before. Turned out my "for sure" diagnosis was wrong, and if I hadn't double checked with a second test I would have swapped a perfectly good part for nothing. It's humbling every single time.
