Helicoil makes a kit just for plugs. They are usually 14 mm. It comes with 3 different inserts to match your plug reach. The kit isn't cheap but it comes with inserts and a tool to lock them into the head so it won't come out. You can get it at any NAPA

I purchased a kit off eBay for about $12.00. Included everything that you need to fix that head.

I'd look for a good used head,either from one of the vendors here or from Fleabay.Personally,I've never had much luck with Helicoil.Especially on a spark plug hole.When you unscrew the spark plug,the insert usually comes out with it.Good luck.

Around here the local auto parts stores has the kits to make that repair, one of my local OPE dealers also stocks them. I have found that a good shot of red Loc-Tite helps keep those coils in place, make sure you let the Loc-Tite dry before installing the plug or you will end up with a plug that can not be removed......... Also a good idea to remove the head because you don't want the metal shavings inside the engine.

I would check local auto part stores that have a machine shop. Take the head

to them and they could install a helicoil for you without any hassles. Just my

opinion.

gonna go on classified and inquire for another one

it looks like the cost of the kit is about the same as buying another one

PM sent on a good head.

A good used head is a good alternative to helicoiling out the hole. If you get it from Kelly, you should have no worries.

IMO...I would helicoil it, (machinist here). Loc-tite makes much better stuff than just red or blue thread locker. We use bearing retaining compound, and beleive me, it aint a gonna come out. After the price for the helicoil kit, you can fix another 5 heads as well. Money in the bank, and another tool in the box. :twocents-02cents:

Chris,is the green loc-tite the compound your referring to? From what Ive read its really strong stuff .

It'll say bearing retaining compound on it. I forget the number 363 or something like that. They make one for a slid fit, and one for a press fit. Use the press fit. After tapping get it clean, and dry. Use the loc-tite, and put in the helicoil. You don't really need that much. Let it dry!!! (You'll most likely never get the plug out ever again if you don't). Yeah...it's that good. No problem with heat as well.

Helicoils are junk go with a keensert or just buy a new head they are cheap and plentiful
