when installing new plugs, never-seize has been suggested to keep the plugs from seizing (obviously) but to protect the plugs from loosening with vibration and blowing out (on older than 2002, 5.4L), has anyone ever thought of using blue loc-tite??

Blue loc-tite is used to keep threads from loosening and is NOT anything like red loc-tite.

I would think the engine heat would break down the blue locktight making it useless!

skrwz, i was looking on the website for permatex, an adhesive company who sells never seize and here's what they said about copper never-seize applications:

shitty, cuz i just bought some of that permatex stuff....copper and nickel (silver). the copper is good to 1800 degrees F, where as the nickel (silver) compund is only good for 1600. Copper states it's used for aluminum (such as our heads) where the silver doesnt state that.
