Spark Plug Repair/Re-thread Kit

I'm sure this has been asked/answered before but I haven't found a direct answer yet:

I bought the spark plug re-thread/repair kit but the Tap end is to large for the 19mm socket necessary to turn it, to fit into the actual hole.

Is there a kit other then heli-coil, etc. that has small enough to fit a socket that can fit in the plug hole? I've read a lot of posts on people who did not have to remove the heads to do this procedure (but not how they fit the tap in the whole), so I'm guessing I have to weld something to the end of the Tap?

thanks

You need the Time-Sert Triton kit to fix these sparkplug threads.

yea I was trying to avoid 380$ given I can buy a new set of PI heads from summit for the same price.

Thinking I'm going to try out the Dorman 42025 kit

its actually what my local ford dealer sells to fix it

thanks for the reply

OP, this is the best possible answer you could get, and you got it from somebody who has actually performed the procedure.

I know the price is a little outrageous especially considering you could almost just buy new heads, but given the work involved in installing new heads vs. rethreading with the Timesert kit, I pick rethreading.

I thought it was outrageous the first time I bought it, but it came with quite a few inserts. I then was thankful the 2nd, 3rd and 4th time I had to use it. Because if one goes, it's only a matter of time until you lose more. My original engine ended up having 4 timeserts in it. Then I rented it out a couple times, and then sold it for $150 to a local shop when I didn't need it anymore.

The last one I did was after midnight in a parking lot by flashlight, and it only took about 30 minutes.

anyone need this kit besides me. i just blew out #3 plug in my '00 GT and with the info i have now i want to repair all 8. the inserts are only 10 bucks each but the $350 for the tooling is alot. i'll split the cost with someone and can offer installation help with repairing yours. the Time-sert kit does appear to be the way to go. who can help with this?
