What do I need to get done? Would a regular speed shop mechanic be able to retap the thread or should I bite the bullet and take it to the stealership. A trusted friend said dealership-helicoil=300.


Thanks in advance.

 

Which of these three would you recomend:

1) Helicoil
2) time-sert
3) Calvan spark plug installer kit

 

any full service garage should be able to do it, i had my buddys shop do mine when i blew one out, i guess there is a kit from ford that works best but i only payed about 150 for the job, and that was the regular price no special freind works in shop discounts haha, try to stay away from the dealer, you WILL get fu*ked in the *** on labor i promise

 

IT IS EASY. take the coil off, run thread sert tap in, put anti seize on spark plug, litely put thread sert on the plug litely, run the thread sert into the threads, remove spark plug, hit thread sert with setting tool and hammer. bingo new threads.

 

use a timesert kit if you can, my friend had a plug blowout, and our friend at the dealership let me use the tool, it pretty much just digs out the old threads and makes threads for the insert, and then u just screw it in. any way you do it though, use lots and lots of grease when drilling or tapping to keep it all out of the combustion chamber.

 

How do you blow out a plug ? Is this a common problem?

 

yes its very common. happened to me. but it got a tad faster after that

 

You have 2 options... well... three, but one is only if you want to sell the car or never change the plugs!

You can Heli-coil it, I tried this on my 1997 Camaro, didnt work, plus you runs the high risk of getting a bunch of metal shavings in your motor.

The best/right way to do it is to remove the head and have it machined at a shop, but this is not easy! I doubt the dealership would heli-coil the head, they would likely remove it... it would cost alot more than $300. at any shop... let alone a dealership!

 

ford dealerships use Timesert kits to repair them.

 

thats why you put vasoline on the tap 2 turns in then back it out clean it off and repeat.
cost me $30 to do mine ( the sav-a-thread kit) and some ingenuity, are the sparkplug sockets on a GT tapered? because that was by far the hardest part, making a new seat for the sparkplug, i didn't think they were.(tapered = levels look down in the hole and see if they gradually get smaller on "steps" to the sparkplug. I sorta rigged it and made it almost impossible for the insert to pop back out because i jb-weleded another insert inside to act as a seat so if it blew out it would simply bounce off of the other one and settle back in the hole lol (the insert/my new threadS)

what i used, i dremeled out another insert to act as a sparkplug seat because it kept wanting to thread the whole way through and i was scared the piston would smash it.
