Blew a plug!!!
I just blew a spark plug on my 2000 Excursion V10 not long after telling my friend (a Suburban owner) how much more I liked my Excursion over the Suburban I used to have. After several phone calls and conversations with Ford mechanics and owners I discovered the real way to repair this is to get the whole head replaced because the threads don't tap well. I was very disappointed to find it will cost $2700+ to get a blown plug fixed. Has anyone else run into this?

Go to the V10 or superduty forum and do a search. It is a fairly commen probelm and ther are other ways to fix the blown plug. I don't know anything more about it other than what I've read but it seems like these are your options
1. Buy a new head
2. Helicoil
3. Timesert
4. Cann't remember
5. A can of gas and a match or a gernade also works J/K
Had to add a little humor as it realy sucks when stuff like this happens. I heard really good things about the timesert fix and it won't cost you your right arm. Do some checking and hopefully this helps you out.

Thanks for the input. If it is such a common problem why wouldn't Ford do anything about it with a warning to check plugs or a recall. That's where I really get stuck. I have talked to a few people who say the helicoil usually works for a few hundred miles if lucky.
Ahh the joy.

My understanding is that it has nothing to do with how many threads the plug has. The problem is with the heads. I heard that Ford changed the heads in '02 and that these provide additional threads for the plug.

I beleive you are correct, the 02s and newer have what I think are called PI heads and it has helped aliviate the problem but I don't know that it completely soved it. As for why ford won't do anything all of us kinda wonder the same thing. Its not just the V10s as I have also heard of the 5.4s doing the same thing. The only thing I know for sure is that it's a really shi%&y thing if it happens to you. I only have 24k on my 03' but it does give me cause for concern. I'm still trying to figure out weather it's better to jsut leave them alone or to change them or to check the torque on them regulary???

I had this happen on my 98 Expedition 5.4L. Happened about 75K, one month after I had the spark plugs changed. I was never able to prove it, but I felt that the dealership cross threaded one of the new plugs. It ended up costing me about $2500, it was the only time I was left high and dry by my Exped. Still have the Exped at 175K, also just bought a 7.3L Excursion, I am very impressed with the diesel. My advice is to find a good mechanic you can trust and use him exclusively.

I have repaired this a few times in the crown vics. Used the Thread-serts and NO problems since. These are taxi cabs too, lots of miles and hard driving. Some repairs over 100,000 miles old, never an issue since I did the thread-sert. Screw replacing the head, don't waste your time/money.

The V10's,5.4's, and 4.6's ALL had the issue. Lightnings had a problem too-supercharged=more cyl. preasure. The thread-sert goes in, and expand as the plug is driven in. The only problem I could think of having is metal shavings getting in, but it's easy to avoid. 2500 to fix!!! Damn, I need you as a customer. I'll time-sert all threads in a V8 or V10 for 1/3 of that and give a life-time warranty for blow-outs.

Ordered replacement plugs for a V10 2000 Excursion with 100,000 miles and they gave me Motorcraft #AGSF22WM.
This is a different number from the original and from what the manual says. They gave me the "superceeding" story.
With all this talk of spitting out plugs, can anyone tell me if these are the correct replacements?
Thanks!
