"those" spark plugs
Ok, so I've read several posts about the plugs in the 5.4 L 3V engine and I'm wondering if I should just go ahead as swap them out now (at 18k) rather than wait till I have 100,000 miles.
I guess the question is are they less likely to break while they are still newer? Does the problem occur in all year models or is it just the 04's?
Possibly relavent info: I have an 05 with the 5.4

Spoke to my local Ford dealer/Mechanic about this a few weeks ago. He mentioned the issues they, as a dealer, were having with them. The 2 on each side, in the back are supposedly the worst to get out. He said definitly do NOT wait until 100k to change them, but said to wait till you have at least 40k on the originals. I've got 9k to go and I'm getting them out.
He also mentioned the TSB removal process to a "T".

Hmmm, after looking over the TSB I see it seems to be directed toward the 04's only. Has anyone with an 05 or 06 had any spark plug woes?

The spark plugs you will find the hardest to get out will be the 2 rear on the passenger side. Driver side is not as bad but still bad. I would change them out so you know the shape. BTW mine is an 06 XLT. No woes but I just wanted to know where they were and if running rich or lean...... if I can get a pic of the ones I pulled out today you will see the white powder build up...... REALLLY LEAN.

I must of got lucky ,,recently helped a friend change plugs on his 01(125,000 miles) .After removing the coils and losing the plugs we squirted PB BLASTER in the holes and let in soak for a couple of hours .The plugs came out fairly easy.We did put anti-seeze back on for easier changing the next time.

There is no reason to change the spark plugs, i have an 05 and read all the woes and headaces with people waiting till 100 thousand mile and wonder why they wount come out. at 10,000 miles i took mine out removed all without any penetrating oil and all came out with ease. had a little carbon on each cleaned each plug and applied anti seize, get the good stuff and reinstalled the same plugs they will go 80 to 90 thousand miles get you moneys worth out of them. and not worried 20 0r 30 thousand miles when i check on them I bet they will come out easy.

Of course spark plugs are not covered under warranty, not even extended warranty. The tech at Ford says that now they are adding a "lubricant/anti-sieze" at the factory to help with the problem. A day late and a dollar short.
