I had no idea that my spindly arms had enough in them to break a spark plug in half, but apparently they do, so now I'm stuck with just the threaded part of the plug in my head and the part that the socket grabs onto sitting in my cup holder.

Someone in another thread had a similar problem and solved it with a #5 easy out. I've poured copious amounts of Liquid Wrench down the hole to try to loosen up whatever was keeping the plug from turning to begin with, and I have a #5 easy out jammed securely into the hole in what's left of the plug, but it's still stubbornly refusing to budge.

Since I've already screwed up once by cranking harder than I should, I'm a bit paranoid that I'm going to put too much *** into it again trying to get the easy out to turn. If I put a cheater on the wrench that I'm using to try to turn the easy out, is there a risk that I'm going to screw things up worse? Any advice would be greatly appreciated.

I will move this thread for you.

 

I've always used PB Blaster, but I doubt its much different than liquid wrench. Plain old WD40 probably wouldn't be enough.

Ordinarily I'd say oxy-acetelene torch on stubborn nuts/bolts, but there's a lot of plastic and gas related stuff in the way. Probably not a recommended method.

I really don't know what I'd do in your case. Sucky situation. Certainly seems like they were over torqued significantly when installed and probably left in there for way too long. I broke several studs that hold the coils on when I did my plugs due to age / long intervals between plugs from previous owner, but fortunately the plugs came out.

 

WOW...those must have been in tight.
Before you snapped the plug, I'd have said try to release the fitting, by slightly tightening the plug firs to break the seal. Then unscrew it. sometimes tightening a stuck bolt or plug, actually makes it easier to remove.
However. Your now doing the right thing, by soaking the plug in a lubricant. Just give it time to work. Maybe give 2 or 3 good soakings over a period of time and leave overnight.
Then, I'd get the best combination of sockets and extentions on a 1/2" ratchet, so that when your "on" the easy out, there's no slop or slogger etc. I'd also personally use a cheater pipe as well, so it's easier to "control" your effort into releasing the plug. Using a cheater pipe will give you this control, rather than struggling away using your full force using just a short ratchet and pushing to excess possibly wobbling or loosing position on the easy out due to this effort.
With a cheater, you can apply a gradual pressure and feel the effort easier imho.
I'd also make sure I had a good position on the tools, so you dont slip or anything.
Go easy, take your time.
If this doen't work....it might unfortunately be, a head off time.
Good luck.
