Here's the hole with the plug in it. Sorry, bad angle...
Attachment 513
The puller in the hole....there is a nut that goes on it to do the actual pulling. And I missed getting a picture of the "pusher" of the ceramic piece. VERY easy to use!

What stays in the head when it breaks off. Again, note the rust, that's what causes the problem. You can see the puller screwed into the plug in this picture. The puller goes inside the piece of aluminum that you can see in the previous picture, and then a left-hand nut threads onto the puller (a plastic washer goes on there too).

Directions
Attachment 510
New materials! I went with Motorcraft plugs again....kinda maddening that they're made in Mexico through...I drive a USA made truck! Make sure to put a lot of anti-seize on them and you won't have this problem the next time (if you own it then...or the next guy). I also went ahead a bought new "boots" that go in between the plug and the coil, they didn't cost that much, and I figured it would be worth it. Make sure to put the dielectric grease on them too.

What one came out as.
Attachment 508
What 4 unfortunately came out as...this is the big design flaw, the crimped on threads pull off of the plug itself. If they come out like this you will need to break the ceramic part...not a big deal, just do it and it's easy.
Attachment 507
What they're supposed to come out looking like. Note the rust on the lower part of the plug, that's what causes them to break off. It binds in the head and when you try to pull it off the outer part is all that comes.Oh, and by the way....you have to pull them out with a socket, you can't just pull the boot off and have them come LOL Yeah, just thought I'd mention!
Attachment 506
All the coils and boots....with some of the plugs.
Attachment 514
Pulling it out! Just so long as they squeak, you know you're good! Just like when you pull them out any other time!
Here's some pictures of pulling the plugs that broke off....sorry it took so long to get them here. The way I tried to pull my plugs was by what one of my mechanics told me, he said he's had only two ever break off in his time. What he said to do was just to get the engine as hot as you can, and pull them out as quick as you can, just so long as they squeak on the way out you know they haven't broken. Start with the hard ones at the back. I do know that there is the danger of messing up the head (since they are aluminum), but I chose to go this way....at almost 120,000 miles then and never having been changed, it probably would've been better to go the slow and easy way as explained in the earlier part of this thread! Sorry some of the steps are out of order...it's really self explanatory when you read the directions that the tool comes with. It is a ton easier than I thought it would be, four of them took 5-8 minutes a piece (at most!) and one I had a little trouble with the threads catching on one. The one I had trouble with only took like 20 minutes, just make sure that if you have trouble with it catching that you don't push the ceramic in too far with the tool the metal piece on the end of the plug will break.....and you don't want to loose pieces in the cylinder. Good luck! Ask any questions and I'll be glad to answer what I can!
