glow plug issue. ideas?

well i went to replace the GPs in the 97. got down the the rear most one on the drivers side and had an issue. the GP has come apart (so far 3 pieces) the top came off with the fuel line, i unscrewed the main body, and the inner part seems to be stuck in the head. i can see it and get pliers to it (not vice grips they are too big). the piece i see moves around when you touch it. i tried pulling it out with the pliers no luck, i removed the diode for the IDM and cranked it over seeing if compression would push it out, no luck. I am trying to not remove the head. any ideas?

I think my next option is to try and pull at teh same time someone cranks the motor over, then remove the injector/rockers/pushrods and see if i can get a better grip. then i guess if everything fails see if i can drive the GP into the cylinder and fish it out, then finally option is the pull the head.

i will add pictures when i go back and take the camera

I've seen the old boy at the shop deal with that a couple time terry. He strips what he needs to in order to get a set of needle nose vide grips on it then hooks a slide hammer to the vise grips. It's a slowwwwwwwwwwwww process. Couple gentle taps out with the slide hammer, tap it back down. Couple taps out, tap it back down....repeat repeat repeat repeat repeat. He worked on the last one for like three hours working it back and forth till it's almost free the spins the engine over and blasts it and any shrapnel out in one good blast of compression.

The end of the glow plug swells sometimes and they get stuck. It happens to every brand name.

What JJ said.

But do not knock it into the cylinder. Because you'll never fish it out.

didn't think of the slide hammer. i have pulled the injector forgot to drain the oil/fuel i did manage to bend the top over

and you're right these were motorcraft plugs

i was thinking if i raise the piston to TDC, then knock it into the cylinder it can't go far but it will now be "loose"

and if i can't fish it out i am really no further behind than when i started

That's why the needle nose vies grips terry. Once you get them clamped on, leave them on. Just tap on the handle of the vies grips with a hammer when tapping it back down. The idea is just keep wiggling it back and forth back and forth. At first the movement will likely be imperceptible.

the one problem with that is where the GP is #8 PITA the firewall is in the way however i will get on it probably thurs. borrowed a borescope from a buddy to look at it from inside the cylinder. have thought about welding the two parts together and unscrewing it. think that will work or think it will break the weld? I guess i need to figure out what metals the two parts are. may wind up leaving it for the time being we'll see. will the GPs work if one is unplugged?
