So i went to change my spark plugs and i was taking one out and it was coming out fine and snap, it came out and stripped the threads in the head.

Any fixes ?
I found these, are they any good ? do they work ?

dude ben I had the same thing happen to me but changing my o2 sensor. I went to autozone/ advanced auto to get a "THREAD CHASER". They have em there for like 8 bucks man.


Edit: But yes that kit will work also. If anything I would go buy a tap that big. They are much stronger than those. Trust me, i ue em all the time at work.

 

Whats the "THREAD CHASER" just a tap that re-taps the hole ?

R U coming down tomorrow ?

 

helicoil will work... but id just try to get a tap

 

yes. Dont go in and ask them. they will look at you like your retarded. which ya not lol. Its called "METRIC THREAD CHASER" for spark plus. But my suggestion would to either buy what ya looked up, od go with the tap. Me I'd go with a tap.



Tomarrow: Im changing out the seat belt and getting my sterion stuff set up for the capacitor when it comes in and then heading to my semi pro baseball game. Tonkaranger04 is on vac. If I have time toommarow I will give ya a call when im coming down!

 

They would work, but I just don't think the "stength" of them will hold up.The tap worked wonders for me!

 

I just used a helicoil on a 96 monte carlo, it worked just fine, my only suggestion is to take it slow and test for compression after you put the new thread insert in and maybe use some high temp RTV to help seal it.

 

anyone know what the size of our spark plugs are/ what size tap would it be ?

 

prob an 18mm





Thats a 14 and 18mm ends

 

a link to determine what size. But im 99.9999999999% sure its 18mm

all those helicoil kits look like they are 14mm x 1.25 assuming that it right what you guys are saying is, I can buy a 14mm x1.25(or whatever the right size is) and just drive the tap in the hole and re-tap the hole ?

 

Yes Ben. That will work 100%. Just take your time doing it. dont rush!!!!!! That will work. But doule check the size

 

oh dear..honistly listen to RETAP the spark plug threads you HAVE TOO take off the head from the motor if any metal chips get into the cylinder oh god would that be bad. the 100% best thing to do... GET A NEW head it isnt worth worrying about a spark plug blowing out on you...

 

this is the thing you dont wanna half-***

 

Very true, I forgot to mention that part.

I agree! there is no guarantee that the tap is going to hold 100% like a new head will.

 

yeah I have a new head well heads on order, but in the mean time I would still like to use the truck. I figured while i am replacing the heads i might as well order a little bit of an up grade so i ordered supersixmotorsports.com stage 2 heads, been wanting to do that anyway.

 

I had a plug just explode out of the head in my VW while going down a hill one day.. I guess it had been cross threaded one too many times.

I had a helicoil installed by a professional mechanic. I didn't want to risk fubaring it and ending up w/ crap in the cylinders. The helicoil held up just fine for at least 20k before I got rid of that thing. I thought the head was done-for when I pulled over that afternoon and found the plug bouncing around the engine compartment on the end of the plug wire. My local mechanic calmed me down. He installed them all the time, said it was no biggie. Had me back on the road the next day..

I suppose you could also retap to a slightly larger plug.. unless the problem is just that your threads are trashed.

But I certianly don't think a new head is called for!

 

Ben, retape the hole for now. it should hold. Then when the new head comes in replace. Thats what i would do.



Edit: Im with stupid above me! lol but really

 

Dude I'm BSing about having heads on order

 

lol i figured. I would still tap it. imo tho

 

Yeah I am, of course its raining and hailing at the moment. According to your link it is for sure a 18mm but 18mm x what ? I guess I will take a plug with me to compare.

I am choosing to believe it was cross threaded from the factory by the way it stripped on the way out. I checked the plug out again just now and the only threads on the plug that are stripped are on the end, which seems very weird.

 

are the threads of the plug stripped/tourn off?

 

Ben I am not kidding on this one at all you want to remove the head to retap or even install a heli coil never do this while its still on the motor...

 

yeah dude... you're gonna have to take the heads off anyways.. ether do it right the first time or you're gonna have to fix what you messed up becasue of not taking the heads off

 

Yes but not many, just a few on the end.
