The day I realized I was torquing cylinder heads wrong for 8 years
I was working on a 6.0 Powerstroke at a shop outside Nashville last spring and the head gaskets kept failing after 6 months. An old lead mechanic watched me one day and asked why I was torquing in a circle instead of following the specific bolt sequence pattern in the manual. Turns out I had been doing it the same way since trade school because nobody ever told me the criss-cross pattern mattered that much with multi-layer steel gaskets. Has anyone else had a shop mentor point out a basic habit you had wrong for years?

Oh man, that brings back a memory! A buddy of mine spent years torquing heads on Cummins engines in a random sequence until his uncle watched him and practically lost it laughing.

Oh jeez, that is way too real. My first year at a lube shop I was tightening oil drain plugs with an impact gun until the shop manager grabbed my wrist and showed me the torque spec in the manual. Felt like such a clown. Sometimes the little things you learn in school stick wrong and nobody calls you out for years.
