I'm about to take delivery of an '07 I ordered, so I've been reading a lot on here. Plenty of plug stories, blowing them out and having them get stuck and break trying to remove them.

The basic question is simple, are these problems almost all gone by '07? I can't find solid evidence, but there are rumors of some minor head changes along the way (more threads?), different plugs, and different anti-sieze from the factory.

Is this something I need to worry about or not?

 

I have an 07 also.....no blow out plug problems on 04-up due to more threads on plug hole.....& I heard from a FORD tech that the plugs only break in head if they are removed incorrectly.........no worries......

 

NO!!! The '07's are developing worse problems than the 04-06 trucks. See, the previous generation 5.4 motors shot plugs out of the head. But the 04+ 5.4 plugs are getting stuck in the heads. But for the 2007 models only, Ford decided to design the 5.4 so that it does both! First, the plug seperates (breaks) while still in the head. That causes the plug insulator to shoot out of the head, and often goes right through your hood. Secondly, it leaves the plug sleeve stuck in the cylinder. The result is that you have to completely remove both heads to get the remants out.

 

That is such a bunch of "CRAP".......if they are removed incorrectly by hacks at dealerships or Shade Tree Mechanics.....then YaH!!!!! One of my best friends is a Ford Tech, he has changed many plugs no worries, unless you have a Hack do the job!!!!

 

You drive a 4.6.....FIGURES......MORE PROPAGANDA from the UNDERPOWERED & JEALOUS CROWD!!!!!

 

Seriously? There's no false information there.

 

Dude - there's a TSB for those who don't know how to change their plugs - I don't have it -don't need it

It's out there , do a search - sounds like you need help

Actually , we use a cordless impact to remove - equalizes torque - no problems - cylinders 3,4 and 8 have to be done by hand - but it's no big deal if you have the recessed 9/16 Ford socket for 2004 motors on up...

 

ROLF IT WAS A SARCASTIC JOKE. GEEZE, LIGHTEN UP.

 

Talkin' to me? Where do you see "4.6" in my sig?

 

To give a SERIOUS answer to your question, no I don't think they've solved or fixed anything in '07 having to do with the plugs. The reason you're probably not seeing any issues with the 07's yet is because they're still too new for anyone to attempt to change them out. But my guess is that time will show them to have the same problems. AFAIK the 2007 uses the same plugs and heads, thus could have the same problems...

That being said, I think that the plug problems for 04+ f150's are RELATIVELY few compared to the number of 5.4's on the road. If you want to be extra sure of your truck, then just pull the plugs every 20,000 miles or so, and apply nickel anti-seize. You should be good to go.

 

If you click on your little camara pic, a 2005 XLT, 4.6, 2WD, comes up.....DAHHH.....now you say that the reason you do not hear of problems with a 2007 cause they are too new to have problems......you are so full of crap, I have to put on my boots & stand on a ladder all the way here!!!!
Get a LIFE!!!!........

 

Makes plenty of sence to me, what morons are changing the plugs in the first 6 months of ownership?

 

Before he stated that the 2007's were worse than others......now he says that they are too new to have problems........he contradicts his own statements and makes no sense whatsoever.........More Crapaganda from the 4.6 crowd......

 

yeh lol seems like alotta supid people buy the 5.4 and change the plugs in them and then mess up the threads or break the plugs so just word of advice.. if u cant change plugs properly dont get a 5.4 or take it to the dealer

 

Yup, you're right. I neglected to update that part of my gallery when I got my new truck in '05. My bad!
