Just realized my old torque wrench method on a Cessna 172's cylinder base nuts was wrong for a solid decade.

I used to go by the book and torque them in a star pattern to the exact foot-pound, but after a mentor in Tulsa showed me his 'feel' method with a calibrated wrench and a final quarter-turn for seating, I haven't had a single leak in three years, so what's your take on strict torque specs versus an experienced final tweak?

Heard the same from a mechanic friend, honestly!

Used to swear by the book myself, always hitting that exact number on the dial. Then I watched an old-timer at my field do his "calibrated wrist" routine on a stubborn O-360, just that last little nudge after torque. Saw how it settled the gasket. Changed my whole view. Sometimes the manual doesn't account for that final real-world seat.
