Spark Plug blew out of head Question

[overlord2kx]

So my friend just got an S13 a couple of weeks ago (Stock KA), and last night while he was driving (Normal, not anything crazy), the spark plug shot out of the head. Not sure exactly why...the previous owner may have cross threaded the plug into the hole or something.

But anyway the question is: Is it safe to re-tap and put a helicoil in? Or does the head need to be replaced? From what I've been reading on other forums, a helicoil should work but Im curious if any of you have had to do this before on a spark plug hole.

iv helicoiled a couple heads on the car and never had a problem. It works just be sure to blow or suck all the metal shavings out of the cylinder.

its possible but a 240 head is probably cheaper than the helicoil

hahahaha, true, but its the small shit that adds up

Man we got helicoils at work like woo too bad im in afghanistan or i would hook you up!

I got a head that just needs to be cleaned and shave if you want it lmk

Its really easy, you should just do a helicoil and call it a day bro.

Yeah, he was able to fix it with a helicoil the other day.

Thanks for the info .

not to thread jack but since we are already on topic.....is retapping easy to do or should a shop do it for u??? and if u re tapped it would it have to be a bigger thread or could it be the same?

Juan, does this help:

My friend never did it before but he did have someone else who worked at a dealer help him. I mean, If you dont feel comfortable doing it, you should probably have a shop do it. If you end up screwing up, the least you might have to do is remove the head, or worst case scenario you might damage the head and need a new one.

But then again, its not THAT hard, so meh.

their really not hard at all, it's basically taping and then threading something into the hole. It will be the same size as the original, if you were tapping only it would be larger but the point of the heli coil is to allow you to put the original size thread back in the hole you stripped.
