You're right, a relatively small percentage of trucks have hit this service interval. So...say only 10% of them have reached it...that's 350,000 trucks! Even if it's only 1% of them, that's still 35,000 trucks...
if all of them needed the heads to be pulled, there would likely be a class action lawsuit.
I agree, there is a problem with the design, which I believe Ford addressed in the '05 and up models by putting anti-sieze lubricant on the plugs from the factory. This is also exactly what the TSB proscribes when putting in the new plugs to insure the issue does not repeat itself.
Flawed design? Sure, you could call it that. BUT, it's been proven time and again that if done correctly, most of the times they come out just fine.
This is all just my opinion here, folks. IMHO an issue such as this shouldn't determine what truck to buy.....I'm confident the original poster will get a great truck no matter what engine he or she buys, but I think he will be better served by the 5.4 if that's what he would prefer outside this issue......

Tom,
Thank you so much for the rant. However I think you misunderstood the point of the post. I was not asking for an opinon on the severity of the problem. I was asking if anyone could confirm the rumor that the heads on 5.4s built after 10-07 had been redesigned to address the plug problem. Nothing more, nothing less.
There have been posts where plugs broke off even though the TSB was followed. It is a gamble that the owner of a $30,000 plus vehicle should not be required to take. The decision on which engine to buy rests soley with the person writing the check. To catagorize people who's opinon differs from yours as ignorant is neither helpful or appreciated!

If EVERY single one of the trucks with the 5.4 broke the plugs when they were being changed, a couple things would be different. 1: Ford would be really hurting, more than they are now because NOBODY would touch one of their trucks with a 10 foot pole. 2: Nobody would be able to use this message board for the simple reason that there would be so many thousands of pissed off people who would come here to complain about their plug problem.
YES there is a problem. BUT if the proper procedures are followed the problem is downright rare.
Not buying a certain engine because something MIGHT POSSIBLY be a problem IF THE REPAIR ISN'T DONE RIGHT is simply ignorant.
End of rant.
On edit:
I really do like my 5.4, but the 4.6 is certainly a great motor, and is proven reliable in over 15 years of use, whereas the 3v 5.4 is a bit newer.
but don't downsize just because you're worried about the integrity of the 5.4! It's also been proven in many millions of trucks, in 2v form from '97 to '03, and the new 3v since 2004!

So if I had problems with plug removal and messed up my heads I could get the new heads from the dealership and put them on my '04?

Hopefully it is not an urban myth or wishful thinking .

Did anybody else notice on page 4 of TSB it said the plug change was elgible[ under the provisions of new vehicle WARRANTY coverage and emissions WARRANTY coverage.

It is unclear whether they changed the head design, plug design or both. Anyway, it appears that something did indeed change in October 07! Thanks to Peterman for posting the link.

Ford will cover the cost above a plug change if the truck was running poorly and NEEDED a plug change. If you decide to change the plugs early and one breaks you are SOL.
Getting a quote in writing is the best advice I've heard. Wish I did that when I had my plugs changed.
