Wasted 6 months torquing injectors wrong because I was using the angle gauge upside down
Had a CPL show up with a snapped bolt head on a 3406E last Tuesday and when I pulled the old one, the torque angle mark was almost 30 degrees off, which is when I finally realized my gauge reads clockwise from the top and I'd been reading it counterclockwise the whole time... anyone else ever had a shop teacher miss that detail in school?

Man, that's a tough lesson. Spin the gauge to zero before you stab the bolt next time.

Read somewhere that even a small crack in the bolt can throw the gauge off by a few pounds. Makes sense why you gotta check the bolt face before you set the torque. Saves you from having to redo the whole thing later.

Yeah "tough lesson" is putting it lightly. I did the exact same thing on a control arm bolt a few months back and ended up snapping it clean off. Had to drill it out and retap the whole thing, so trust me @benw87, your tip about zeroing the gauge first is solid advice.
