I'll be changing the glow plugs and relay in the truck in my sig in the coming week, of course, only using Motorcraft plugs and relay. My question is, does anyone know the torque spec for the glow plugs? I've found answers of 124 in lbs, and also of 14 ft lbs, which equates to 168 inch lbs. Correct me if I'm wrong but the valve covers should be 97 in lbs.
