ok, i know this is a real old thread, but i just want to confirm that last comment for anyone reading this. There was an extra "sound" at idle for a little over a month before my plug blew. would have been nice to know that before hand. I usually do all of my own mechanic work, but i was out of town and my dad had my truck when it happened. friend of mine tried looked at it and tried to re-tap the thread, but couldn't get to it. When i got home, i just started pulling the motor apart and when i got the air intake out of the way, i re-tapped the hole to a bigger size and added the insert. Now i have to figure out how to put everything back together.

I just had the same issue happen tonight on my V10 SD, 4th plug back from the front passenger side.
Had a ticking sound that sounded like an exhaust leak for the last 3 days and couldn't find where it was coming from... Well I found it today while hauling a tractor and the plug let loose.
Does anyone know of the correct way to repair this so I dont run in to the same issue again or do anymore damage then is already done?
It blew out the plug and shattered the coil pack, I was running about 2500RPM up a hill when it blew out.

I'm going to see if I can find somewhere local that sells the time serts and see how hard it looks and go from there, I can't afford to pay ford top dollar to fix something they know is an issue and wont do anything about.

Unfortunately they won't let me cross the border without a passport lol.

You're failing to mention that YOU changed the plugs 2500 miles ago.

I'd like to know how, changed them at 101,000 miles when they recomend 100,000 miles. Torqued them to the specs the service manager at ford told me to and the admitted to knowing theres a problem with them\. I can gurantee you this will be the last Ford I ever buy new or own.

NONE of the trucks in our fleet has ever had a problem with a spark plug.
Every single instance of spark plug "blowout" that I've dealt with was the fault of the installer whether it be the original engine assembly line worker, or the guy changing them at a later date. I have never seen a properly installed spark plug on a modular "blow out"-it's that simple.
The problem you have was listening to the service manager. The only times I have ever seen problems was when people were using a torque wrench on these, or if they were driving around with the engine detonating like crazy.

Nope, I meant it exactly as I typed it. Using a torque wrench on these plugs is asking for a problem. The largest percentage of the people out there are NOT using a torque wrench that has been recently calibrated(hell, most don't even know they have to be calibrated regularly), and the get banged around in the shop or used on things like lug nuts,and then people expect them to be accurate at the lower end of the scale on something like aluminum cylinder heads.

I never use a torque wrench on plugs except my outboards where I can get an accurate torque, all others snugged by feel. Regardless if the wrench is calibrated properly or not I'm not seeing how you get an accurate torque without using the proper lube, especially on a tapered seat plug. Then add in the confined space and inability to get a straight shot on all plugs.
Your going to have a hard time finding anyone local that sells the timesert kits. They will only have the junk Helicoil kits. Most dealers do not install the Timeserts, they install some inferior knockoff or want to pull the head. What dealer did you go to, Manderbach? Best bet is to order a Timesert kit off the internet but they are not cheap. They also have to be installed properly with ALL shavings removed from the cylinder.
Sorry to say your plugs were more than likely installed too loose, came loose and one launched.

One thing to remember is to remove all tension when storing them.
