Just realized I've been torquing injector hold-downs by feel for 15 years and that's why I kept chasing leaks
Used to just snug them down with a 3/8 ratchet and call it good, figured if it felt tight it was tight. Had a 6.7 Cummins come back twice with a fuel knock and I finally broke out the torque wrench and hit 44 inch-pounds in sequence like the book says. Haven't had a comeback since, that was about 8 months ago. Turns out my 'feel' was about 20 inch-pounds on some and 70 on others. Any of you guys got a spec you ignored for way too long because it always seemed to work out?

My grandpa was a carpenter for 40 years and always said "measure twice, cut once" but he never owned a tape measure, just eyeballed everything. Same deal with torque specs, we trust our hands because they've worked before, until that one job where they don't. Feels like half of getting older is just admitting the tools exist for a reason.
