You have to get them out. Do NOT push/ hammer/ force them into the cylinder OR you will have to remove that head. That may be your only recourse, to remove the head and then force the plug out. Good luck Mack22 and Welcome to SDD. I am sure others will chime in...

Do a search on the topic of glowplug replacement and you'll get what you need. I fortunatley didn't have your issue when I did mine.
I would for sure replace the valve cover harness and if needed, the under valve cover harness for each glow plug. Good relativly cheap insurance while your under there even if they look good.
Now, if I could just keep my tranny working !!!!!!!!

welcome to the forum. And when you replace your glow plugs dont buy AUTOLITE, buy Motorcraft (Beru).

Push them back in the hole so you can run/drive the vehicle. Take the fuel filter lid off and drain out enough fuel to fit a full can of Seafoam in the cannister. Then drop at least another full can in the tank, maybe two cans and run that tank through also. It might help get the tips of the GP's cleaned off so you can get them out.
As Dave mentioned though, you need to get them out whole, not broken and pushed into the combustion chamber.

Welcome to the forum!
On the harnesses, if any of the external or internal connections to the valvecover gaskets are burned or melted, obviously replace the affected harness (internal) or connector (external). Also replace the gasket ... otherwise you'll be be doing the repair again shortly. High resistance connections (and small gauge wiring) cause the problem in the first place. Cheers!

definatly change the uvch's and gaskets, and if needed the outside connector as well.welcome to the forum!
a very crude and not so safe way to get stuck plugs out is to crank the engine over and SHOOT them out. they are like bullets, and will go through/damage whatever is in the way. this is a last chance attempt before removing the heads. you will want to disconnect the cam sensor so the engine wont fire, if it fires you will be sending a glowplug to the moon.
i have found i have better luck removing them when the engine is SMOKING HOT. like so hot you really cant touch anything on it, but you have to....so have some COLD beer ready.
i have also talked to people that say extreme cold helps as well.....never tried it myself.
good luck and keep us informed.

Did you try cranking it over? If you don't want to do the work I have someone to recommend. One man shop reasonable price.

dont crank it over!!!!! think of the concequences!! you have roughly 400 psi of compression and you are going to try to BLOW out the glow plug tip????? ive seen them got thru the metal valve cover and dent the hood. VERY BAD IDEA very UNSAFE!!!
