My uncle said to always use a torque wrench on injector hold-downs, but the old head at my shop swears by 'feel'.

I snapped a bolt on a Duramax following the 'feel' method after my uncle warned me. Who's right here, the manual spec or the experienced hand?

Honestly that old head's "feel" method has kept more trucks running than any manual. You gotta understand those specs are for a perfect, clean bolt in a lab. Real world stuff gets corroded, threads get tired. A guy who's done a hundred of them knows the real feel of when it's tight before it sings. Your uncle isn't wrong for new parts, but experience trumps paper for old iron.

Totally agree with @emery_taylor3, my hands learned that feel long before I ever saw a torque wrench.
