What happens if I over tighten spark plugs?
What happens if I over tighten spark plugs? An over-torqued spark plug can cause stress to the metal shell, leading to thread damage or breakage. Over tightening can also compromise a plug's internal gas seal or even cause a hairline fracture in the insulator. Where does the water come from in a Ford Focus?
