I just want to know the procedure for fixing a stripped spark plug hole. I havent taken the plug totally out yet because i am still drivin the car and have nothing to tap the hole with.. but what would the procedure be for this. I´m afraid of the shrapnel that will get caught in the chamber, but i know this spark plug is atleast 50,000 miles old ( the guy i bought the car off said so, for $250 i didnt care) its a rusty mess
Ive got an 86 gt... help me out? thanks

i would think you´d have to take the head off to re-tap the hole.

Are we talking about the threads being stripped, or the 6 sides o the plug itself? if its jus the plug, break the top off and hammer a smaller 6 point socket onto it. if we are talking about threads, tapping would be a mistake, the hole would be bigger and the plug would not be big enough. instead get a heli coil kit. damn good but yeah your gonna have to pull the head.

You heard it from the pro´s...
hehe
anyway, good luck with that one, and i´m not surprised if I end up with the same problem here before long. I bought a 93 off a guy for $700. and everyday I´m finding something else I need to fix to get her reliable.
anyway, anybody have an extra pulley that sits below the compressor on the 1.9. Mine is dented and wobbly, that´s my first project..
thanks..
any help would be greatly appreciated
I HAVE JUST GOT TO GET THIS THING ON THE AUTOSTRADA!!
hehe

AntiSieze would have prevented that it keeps the threads clean. That sux dude.

Ah antisieze. the copper stuff tastes really sweet on chicken mcnuggets. if you don´t believe me try it yourself. just a little dab is all you need. but really- antisieze and not cross threading the plugs when they go in is the key to the whole thing. when you put in a spark plug the first couple turns should just be you spinning the socket and extension with you fingers. this should not be tough going the whole way. if it is clean the shit of it and try again.

... i looked up the problem online... i need a helicoil kit.. the threads are stripped but if you read above i didnt do it.. the previous owner probly started cross threading and said ahhh fu*k it and threw it in all the way... i always use anti seize... and ive never stripped a plug... so ive never dealt with it...

oh and heres another problem i might come across.. i might not be able to get the plug out.. the reason why i stopped trying to take it out is because i was putting about 25lbs/ft of tourque on it to get it out(turning the right way ... come this weekend im gonna let the engine heat up nice and go for the gold... as long as its out ill be alright with a helicoil kit.. they also say not to take off the head... ill figure it out tho

[birddog]

are you sure the threads are stripped? If you are puttin some grunt to it and it won´t turn, the threads aren´t stripped. And I wanna see how you drill out the hole for the heli coil without getting metal in the engine if you don´t take the head off.

 

[CosworthWannabe2]

Heating it up will only make it tighter The plug will expand but the aluminum won´t. If it was a cast iron head that might work. You´ll have to pull the head regardless.

 

[86gt]

If i heat the engine up im not sure how much that will help.. your right about the metal... im going to soak the plug/hole with wd40 before tryin to take it out for a day or 2... what im thinking it might be is rust.. the engine is fairly rusty.. for an 86 it makes sense so im not sure if its stripped or not.. i hope with some lube the plug will come out....

any suggestions for loosening up the hole? different lubricants? im even thinkin i have this can of rust eater i might put on the problem...

also, im patchin some holes in the trunk area and after im all done i want to coat the inside with some sort of spray coating/foam insulant to quiet the inside of the trunk.... anyone have good ideas?

[CosworthWannabe2]

For the lube for the plug get some HoneGoo it´s the best, keep filling the hole to the top for like three days and hope for the best. If all the Goo dissapears then you know it´s gone past the threads and into the cylinder don´t worry it will just smoke for a few minutes. Try loosen the spark plug up abit just enough to separate the plug seat from the mating spot on the head.

 

[86gt]

sounds good.. where could i find some honegoo?... is it made by goo gone? i know what you mean about the loosening up part, it took a while but i understand.. to let some goo in the threads.. thanks

You may, or may not like this idea but I have had two escorts now and they both leaked into the right side trunk area. I drilled two small holes in that area. One in each pocket area. Since then I have never had another wet carpet or pocket there since and my rusting process has stopped. Now i´m going to remove as much rust as I can and paint it with a primer. Thats what I would recommend first, then you can buy that spray-in noise dampener.
Anyway, hope this helped

maybe this will post in the right place this time. If not see my other response.
Mike, I drilled two holes in my right side pocket and no more rust. And then just paint the trunk with some primer and paint or primer then the noise deadener spray.
anyway, if you see my other response first, its a little easier to understand then this one...this damn computer sucks.......its so slow.....
anyway. later

Good news! with some lubricant... the spark plug came out and was not damaged.. just rusted... so i cleaned out the hole and used anit-seize... i jus finished installing new rear struts, and patching some holes... i bought truck bed liner spray.. but havent done up the back yet.. its going to be nice... as for water build up.. i havent come across any yet.. but if i see a pocket of water.. i might just drill a hole like you said gmoney... the only thing is i dont think that the inspectors like holes... man made or rust... so we´ll see...
