Was dead set against torque wrenches on spark plugs until a 737 threw a cylinder last spring
I've been turning wrenches since the late 90s and always thought I could feel when a spark plug was tight enough. Then we had a bird come back from a turn with a cylinder head cracked right at the plug hole. It was a -9 on a 737 from the old Delta fleet. The guy before me had cranked it down too hard. Now I use the Snap on torque wrench every time and haven't had an issue since. Any of you old timers ever get burned by skipping the torque spec?
