Had a guy at the hardware store in Flint tell me my torque wrench needed a calibration check
He showed me the difference on a bolt between my wrench and his digital tester and it was off by 12 foot-pounds, which explained why my engine rebuild last spring kept leaking oil.

Totally agree with @blair_nguyen on that, 12 pounds can wreck a whole job. Sucks how something so small can cause such a headache.

12 foot-pounds is a bigger deal than I used to think, but after my own torque wrench failed on a head gasket job I totally get why you'd want it checked.

Ha, man, that's the kind of stuff that keeps me up at night. Honestly, I had a buddy who swore by his old beam-style torque wrench from his dad's garage, never checked it once. He did a rear differential rebuild and it was leaking like a sieve a month later, total nightmare. That 12 pounds off might not sound like much but on a small bolt it's the difference between sealing and stripping. It's wild how one little tool can mess up weeks of work.
