Spark plug suggestion.
I spoke to someone over the weekend, that works or did work for Ford, regarding the spark plug issue. I was told that Ford has stopped putting brake seeze on the threads of the spark plugs do to saving costs. If this in fact true then I'm goiing to remove them and lube up the treads, put them back in and replace them at the recommended 100k miles. Plus I just priced them at $12.97 per. and $7.97 for the originals.Just wanted to relay the message.

There's a reason for not putting antisieze on. It makes additional spacing between the plugs and the head causing them to loosen up. This in turn makes them vibrate and blow out of the head. which is what every person on here whines about. There is a reason dealerships don't use antisieze on plugs, so it's in your best interest you listen. Or don't bitch when your plugs blow out.....

I beleive he is refering to the issue of not being able to get the plugs out in 04 and up 5.4 engines, these plugs have 7-8 threads and won't blow out they come out very hard due to close tolerances in the heads and carbon build up.

Well if ford thought antisieze should be used, they would have put it in from the factory. No bulletin I know of said use antisieze. and every tech I work with never uses it. It also contaminates the plugs..... bottom line if ford certified techs don't use it, why would a home mechanic want to??

This was posted in the 4.6,5.4L Modular Engine forum on this site referring to the 5.4L 3V engine:
NOTE
ONCE THE SPARK PLUGS HAVE ALL BEEN
REMOVED, NEW PLUGS SHOULD BE
INSTALLED USING A FILM COATING OF
MOTORCRAFT HIGH TEMPERATURE NICKEL
ANTI-SEIZE LUBRICANT (XL-2) ON THE GROUND
ELECTRODE SHIELD OF THE NEW SPARK PLUG
(FIGURE 7). DO NOT COAT THE ELECTRODE
STRAP OR THE PLUG WILL MISFIRE. THE NEW CONDITION PLUGS SHOULD BE INSTALLED WITH
NO LUBRICANT ON THE THREADS AND TORQUED
TO SPECIFICATION, 25 LB-FT (34 N•m).
Pretty much sums it up.

First off I'm not a tech(YET)....I'm an intern at a dealership. I'm still going to school for this. And everyone(including my teachers) tell me not to use antisieze on plugs. Secondly, I've never seen a 5.4L (that I can remember) that used the plug posted after your comment(with the extra spacing after the threads). Every plug I've ever used had the 7-8 threads then the electrode(which you can't use antisieze on these because it messes with the grounding of the plug as well as if it gets on the electrode will cause misfiring)or the old 3-4 thread used in the troubled heads..... I"m just going by what I"ve been told by techs with years of experience.

YO wilber, The Ford mechanic I am referring wouldn't have any reason to lie first of all. Second, your making comments with no proper backround other then being an intern and a student. You may want to get used to these plugs because if you pass, you maybe repacing these broken plugs.
