Took advice from a 30 year A&P to stop torquing spark plugs by feel
Old timer at my hangar in Tulsa told me I was wasting time using a torque wrench on spark plugs, so I stopped for a few months. Then I pulled one out during a 100 hour and found the threads were starting to gall from being too tight. Has anyone else had a seasoned mechanic give them bad habits?

Did you check the manual for torque specs or just go with what he said?

Did you ever find out if that old timer had been doing it that way for 30 years and just got lucky, or was he passing on bad info he actually believed? I had a guy at a shop in Amarillo tell me to never use a multimeter on a running engine because it would "fry the computer", so I went a whole year thinking that was true until a buddy laughed at me.
