So wensday i blew out #2 spark plug not even on the gas, able to coast it to buddys house. It's all good try it again it's stripped bought save-a-thread ended up welding 7 or 8 bolts on it to be able to fit down to the threads. Had in as far as i could get utill it would not turn, put the heli-coil into it and it's about 1/4 of an inch higher than the rest. So anyways i've been driving around with a high spark plug the last three days keeping it under 3600. The engine runs amazingly better than when i first bought it. So i was wondering what your opinion are on the high plug should i be expecting something to go soon on the engine. Would i still be getting any spark to that cylinder?

Thanks

I searched.

The only problem that I could see would be that the heli-coil and sprark plug might blow out agian. It will still get spark in that cylinder and run fine, but if you ever remove the head I would definitely have that fixed.

As long as the plug isnt farther down into the combustion chamber, you should be alright. I've heard of that happening but have only seen it done once. Goodluck!

The *best* way to do this would be to take the head off, and helicoil the threads from the combustion chamber side of the head. This way, you can match the thread mating surface even with the head. This, along with possibly getting metal shavings into the cylinders, is why you should really take the head off to repair it. Considerable amount of work of course, but it will be done right. BTW, helicoil's are strong as hell, and even make the threads stronger than the original's. I've heard that a lot of aircraft applications use helicoil's for added safty and strength. I had to use a helicoil on my head, for the timing belt idler pulley bolt hole. It's been holding strong for thousands of miles now..

Thanks for the reassurance, i today replaced the vc gasket along with spark plug gaskets and it running really well there is quite abit of difference without oil in the plugs.
I do plan on taking the head of this winter and getting it proffesionally to just to be safe.
