TIL a lot of guys at my hangar are using the wrong torque sequence on cylinder base nuts
I was helping a new guy button up a Lycoming O-360 yesterday, and he was going around the base nuts in a circle... like lug nuts on a car wheel. I stopped him right there. I learned the hard way on a Cessna 172 years back, doing a top overhaul and getting a small oil leak from a warped flange. The book says star pattern, working from the center out in steps, and it matters. Those cylinders have to sit flat on the crankcase, or you get uneven pressure and a path for oil. It seems small, but seeing it twice this month alone makes me wonder if this is getting missed in some shops. How do you all teach the right sequence to new mechanics?

Manuals get ignored? People actually read those?
