I JUST had this done. The dealer, Landers Ford in Collierville TN, screwed up and misdiagnosed a ticking sound in my engine last month as a lifter problem. Turns out it was the number 8 plug...it blew one month later.
The dealer told me I'd have to replace the head for $3,300 or buy a new engine for $5,000.
Some very helpful folks here on the forum turned me on to Time-Sert.
Dyno-Speed in Memphis TN did the job in 4 hours for $371. I have the truck back...runs like a top and no more ticking. Long live Time-Sert! Long live Dyno-Speed!
It might help to find a shop that has done these type of jobs in the past....they've already got the kit. The kit itself costs more than they charged me to do the work.
If you need to buy the kit Time-Sert has a list of authorized dealers on their website.
Usually occurs after a plug change. The problem is well documented but Ford is so broke they won't acknowledge the problem. Google "Triton Engine Spitting Spark Plugs" are you will see more than you want to see.
Many opinions about the topic. Careful removal (Carbon hurting threads), cleanliness, anti-seize and 13-15lbs torque. Some folks suggest not changing the plugs ever......
I think it consist of: the new thread tap, the timeserts (peice of metal that is threaded on the inside for the spark plug and the outside for the tap that comes with the kit) tools to install the timeserts, and a small amount of grease(that way when your tapping into the spark plug hole the grease catches the shavings)

I just had a blowout on my 02 f150 which has only 42k on it. i was only going 20 mph when it happened. the ford dealer said they charge $500 to fix it. i found a good local mechanic who did it for a little less. they recommend not even changing the spark plugs if you can help it. the carbon build up on the bottom threads may strip the holes if you take them out. ford needs to do something about this. its too bad, cause i love the pickup.
