Snapped spark plug
I pulled my plugs just now to do a compression test, upon re-torquing number 3 plug it broke
Im assuming im not the first person to do this...... (I hope) and I'm wondering what I should do now. I fear that I will have to pull the head..... again. After all of about 25minutes on a brand new gasket
Would it be safe to use an easy out to get the remaining portion of the plug out, then vac out any filings that would have fallen into the chamber?

On the positive side - My compression was okay :S

Get it out how ever you can and vaccum it will be fine. I have also just used a blower tip on the air compressor and blown the junk out of cylinders before. Not damaging the threads is going to be the hard part. But that can also be fixed with the head on if needed too.

Did the plug actually break between the hex head and the threads? I have broke many plugs between the hex head and the porcelain tower, but that only requires "backing out" the remaining portion of the plug. If, in fact, the plug broke off below the hex head that would be a first in my experiences. Can you share a pic of the piece that broke off?

Had one do that years ago in my truck. I just used an easy out and removed it. Some heavy grease on the easy out may even catch any shavings to prevent them falling into the engine.

Got it. Thanks guys. I used a flat head screwdriver and gave it a couple of taps on the bottom, just enough to wedge it in the hole. With a bit of patience I managed to back it out. There's a few shavings sitting atop of the piston that I'll try and get out with a magnet otherwise I'll have to get a vac.

BE VERY CAREFUL with an easy out. if you break the easy out off inside the head you will have even more problems.

Had that happen to my ski once, used a long flat headed screwdriver and was able to unscrew the threaded piece of the plug out.
