The last time I had my plugs replaced the mechanic said he was unable to remove one of them. I suppose it was basically stuck. He said to remove it would require some other means which I don't recall. Can someone please elaborate? What are the implications of this?

 

:eek3: did they seize in the block? damn... thats gotta suck

 

if the plug is seized into the head, and there is no way to break it loose, the only thing i can think of is pulling the head off and basically drilling it out.

 

I don't do any repairs to my car, so how involved would it be to drill it out?

 

very, the head of the engine would be removed from the block, then the plug would be drilled out, and the head reattached to the block - good opportunity to replace the headgasket.

 

I would say first things first, soak the shit out of it with WD40, PBBlaster, Silicone Spray, whatever you have.

If you cant loosen it with a ratchet, slide a pipe over the end of the ratchet for more leverage. If its stripped, itll just spin. If its stuck, you have to be able to get it out. Worse comes to worse you get the ratchet, extension, a long pipe and a hammer...itll come out.

 

If all else fails, get a bigger hammer...

 

Along with the anti seize and plenty of leverage posted above, make sure your using a deep well six sided socket so it doesn't round out on you.

If it's already rounded, Sears sell really great extractors. Better than others because the top allows the tip of the plug to pass through a hole instead of having to bust off the top of the plug and possibly get debris down into cylinder.

 

Good luck, i busted off one on a vintage N600 motor once and had to pull the head. It messed up the hole pretty good.

I would just go for it and if it breaks so be it. At least in the end you'll have fixed it. Next time make sure anti-seize gets on the new plugs.
