Stripped Spark Plug Hole......Need Help ASAP!

Stripped Spark Plug Hole......Need Help ASAP!
So I went to start my truck today and the back spark plug on the drivers side blew out. I just bought the truck and it has newer plugs and coil packs so I'm assuming the person who installed those cross threaded the hole and made it weak.
My question is what the heck do I do from here? I don't really want to tear the head off of the truck or tear the truck all apart. Is there a product out there that is designed to fix this while the head is still on the truck?
Any help will be greatly appreciated, thanks.

You can get a helicoil insert to repair threads, but those require that you drill and tap the original hole to accept the insert.
I don't know how you could drill and tap in that space (I think the driver's side is better than the passenger side from what I remember when I had my 5.4L).
It would be tough to get all the cuttings out of the cylinder. I suppose you could vacuum and inspect with a borescope.

This is a common problem, do a search on it. Here is a link to a good write up on fixing it: https://www.ford-trucks.com/forums/9...th-photos.html
From most people on here the Time-Sert kit is the best way of doing this. Also go to there website for info on their repair.

Yea I saw one of the threads and they are kind of hard to read. Alot of replying without any info (atleast the thread I saw).
I did find some kits at advanced like the Dorman Kit, it was about $75. which is way more than a heli coil kit so I was wondering if anybody here has had any experience with them?

Will a Helicoil allow the explosion to blow by? I can see how that might be a cause for concern.

Since I recommended Helicoil, I was just wondering why it is the worst. I work as a design engineer and we send tools on top of drill bits 20k ft into the ground at temperatures like 300 degrees and pressures to 25ksi. Of course the inserts are not open to the drilling fluids or anything, they are embedded in the tools.

The time-sert is the next generation of threaded inserts. They are solid, and are expanded during installation - forming an interference fit that is much less likely to back out. Yes, they cost more, but are more reliable in critical applications. I've NEVER had a failure.
And I find them much easier to install correctly - expecially in difficult to see locations.
Check them out - a great "tool" to be aware of!

Well I went out tonight and bought the Dorman kit from advanced auto parts. I think it was 56.99. To me it almost looks to easy, but I will try it. I will post later if it worked or not.
Basically you just screw this tapered deal into the old hole, thread it till its tight, then you screw this elongated spark plug into the first guy and its done............. We will see. Supposedly the part taps a new hole while containing all the shavings, your just supposed to screw it in once and not back it out.........
I will post an update later.
Thanks for all the replies.
