[QUOTE=Lime GT;6785965]
Thanks. I actually already printed out the TSB.
I decided to replace the plugs with brand new Motorcraft plugs. When I am able to pull the plugs out,(can't do it for a while, recovering from upper back surgery right now) they will probably be fine. However I want to check them and if I do not replace them, I will put the Motorcraft anti seize on them after I clean them. Sure, they may last 100K miles, however I will check them so I know everything is good.
Thanks again!

Have any of you replaced your plugs to avoid this problem of the OEM plugs breaking off or do you think that the stock plugs will last up to 100K miles and just to leave it as long as it is running good?
Additionally, has anyone had plugs break and how tough was it to remove the broken part of the plug?
Any TSB on this as well?

You already have the best plug in your vehicle in my opinion. I've never had good longevity with Champion Plugs. I have my own worries with the one-piece plug. Say if the barrel sticks bad enough to allow the plug to break, where will it let go? Maybe between the thread and the hex nut? I don't know but don't want to find out. I've change two-piece plugs at least 4 times at work in Expeditions and never broke a plug using the TSB and pre-breaking loose the plugs and then letting them sit overnight with the Ford cleaner spec'd in the TSB. Some of these trucks had in excess of 60000k on them. Yes, when I removed some the barrel did come loose but they never separated.
Here's the TSB... http://www.phila.gov/fleet/Warranty%...-06%20FORD.pdf

I remember doing my plugs like it was yesterday. My car had just over 30K on it (back in 2009). Its not a daliy driver, but I wanted to get them out (and replace them) and see just how bad the carbon was. My dad helped me out (60+ year retired auto mechanic who rebuilds classic Model A cars among other classic cars). We followed the TSB to a T. Loosen the plugs 1/8 of a turn, pour in a small amount of the solution (forget the name) to help break up the carbon build up.
The 1/8th turn was easy. Once they soaked for about 1/2 an hour or so, we took them out. A few came right out. A few others took some elbow grease to get out. Luckily they all came out in one piece. Put the new Motorcraft ones in, after putting anti-seize on it and so far so good. Car just turned 35K and I'll check them in another 5K. Moral...take your time and follow the TSBV and everthing will be fine.

Um... not tooting my own horn here, just thought I'd help. Seemed it was well received last time... also some other good advice in that thread too.

Hope that helps, and don't panic.

I did mine this weekend on my 08 with 12k on the clock. I did mine several years ago on my 05. Last time I broke one. This time they came out as smooth as butter. This time I used PB Blaster and last time I used Kroil Penetrating Oil. Not sure if that was it but this was a very simple swap. Put in Champions. I am done changing plugs so if you need a Lisle removal tool let me know. Good luck!

Yes, it is a garage queen
On the PB Blaster, was it a spectific type? I guess they have different types, oil and catalyst???
Thanks again!

The PB Blaster was the spray can off the shelf at Wal-Mart. The concern was how much to spray into plug hole. Too much and you have to worry about hydro locking the cylinder. I took a plastic sandwich bag and practiced a few times spraying into the bag and counting to three or four and seeing how much oil was in the bag. Then when I sprayed into the plug hole I knew it was not too much. I also used the Techron fuel cleaner in a few tanks of gas thinking it may help loosen or do something to the build up of carbon. That too is six or seven bucks at WalMart. Perhaps over kill but the thrill of having a plug break is an experience you never quite forget! Have fun you will do great I am sure!!
