Broke a glow plug and need advice

[btbellefleur]

broke a glow plug on the passenger side in the rear of the engine. the piece is big enough to get needle nose vice grips on but refuses to budge. ive tried pb blaster, twisting, pushing, pulling, and have been unsuccessful... i dont really want to take the head off considering i dont have a place to do it myself and dont have the money to have someone else do it. am i ok to run it with the one plug inactive?

the piece of the plug that is in there is the hollow tube where the wire runs through and the tip that heats up. the sleeve with the threads came out

You could try some Mercury Powertune on it and some more twisting/pulling to see it will work loose. It may take awhile! Cheers!
