I judged a guy for using anti-seize on spark plugs, then my mechanic in Boise showed me his thread gauge
For 12 years I thought anti-seize on plug threads was a rookie move that would throw off torque values, but when my mechanic in Boise pulled the plugs from my Continental IO-520 and showed me the stretched threads on cylinder 3, he asked me one question: how many aluminum heads have you pulled plugs from with a dry socket at 500 hours?
