TIL I've been torquing head bolts wrong for years because of a bad habit from my old boss in Wichita.
He always said to just 'go by feel' on a Cummins 5.9, so I never used a proper torque angle gauge. Yesterday, a guy at the parts counter asked if I was using one, and I felt like an idiot. It finally clicked why I've had a few come back with minor leaks. Anyone else get stuck on a bad practice they learned early on?

My uncle ran a shop in Tulsa for thirty years and swore by the "three ugga-duggas" method for lug nuts. It took a snapped stud on my own truck to break that habit. You see it everywhere, from cooking to home repair, where a shortcut becomes gospel. Hard to unlearn something that feels right in your hands, even when the numbers prove it wrong.

Spot that in old work manuals too, where a quick fix gets passed down as the only way. Muscle memory beats the manual every time until something breaks.
