DR3W, you blew out a spark plug. Did you change your plugs about 5,000 miles ago? You can attempt to thread the plug back in, but eventually it is going to blow out again. TRUST ME. Now, with this being said, I can save you a lot of money. I have the Timesert Kit and all that you would have to do is pay for the postage to get the kit out to you and back and the new sleeve ($12 plus S&H).
As for doing the sleeve bit. You have 2 choices when it comes to this. You can: 1) do the single plug, keep the head installed on the engine and just make sure to pack the tools in the kit well with grease when cutting the aluminum in the head, or 2) pull the heads off of the engine, do all of the plugs at the same time and not have to worry about this ever happening again in the future. The second way is more work, but at the same time, it gives you a sense of security knowing that you now have 6 threads holding a plug in place, not 3 like Ford put into the head. Removing the heads would also give you a chance to do some porting and polishing to get some more horses out of the engine. I did a mild port/polish on my truck for around $30 and a few hours of my time. You can pull the heads, insert the new sleeves on all 8 plugs, and do a mild port/polish in a weekend. Granted, all that you are going to do is this. If you skip the porting/polishing, plan on about 16-18 hours of wrenching to do all the work necessary. I chose option 2 as I wanted the peace of mind to not have to worry about it again. It is the more expensive route, but the peace of mind is wonderful.
