Default Stubborn seized glow plug..

I have the air tool from MA to assist in removal of stuck glow plugs. I've been at it for 3hrs, and have backed it out 1.5 turns id say. I started the engine at operating temp, and have soaked the plug the last 4 days. The engine is now just warm...being the glow plug is backed out some, am I safe to drive the truck to get it back up to temp again to help free this glow plug back up?

I have a small butane torch, and used it to heat up just the glow plug. I'd wait 2min or so after heating the glow plug, hit it with some pb blaster, and try backing it out. This worked for a while, but it seems since the engine has cooled down more and more, its now pretty tight again. I'm going to wait a few hours, and go back out and try getting after it again. I get maybe 1/32 of a turn whenever it moves, and theres alot of time between when it moves LOL. Patience will be my friend with this damn thing..

When I go back out, I'll turn the butane up and try and heat up the head around the glow plug. It'd be ideal to just drive the thing and get it back up to temp, but I'd hate to hurt the head/glow plug bore somehow.

I had one like this myself awhile back due to inj cup leaking. Coolant and possibly oil cooked around the glow plug probe itself . I thought threads were the prob but I finally got pissed and hooked my 3/8 IR impact on that bitch and spun it for awhile . All the grime etc that was stuck to it and the head broke loose and came right out.

I dont have the balls to use a 3/8 impact. I'm hoping with patience, and heat, I can get it out. I'd rather live with a bad glow plug, then get overly anxious and break the nut off. I'm already starting to loose hair, and breaking the nut off would for surely speed that process up a bit...

You want to heat up the metal around the plug not the plug itself.... heat makes metal expand so heating the plug is just making it expand in the threads

Hambone, I told myself the same thing, but for a while it was working

I'm going to go back out there soon and get back after it. To be honest I was getting wore out LOL. The nice part is it's cyl2 so its not too bad to get to.

So I've read! If I dont make much headway heating the head, I'm calling my buddy to run me into town and try and find some.

From what you said it sounds like it was working because the block was still warm.

I have a small dewalt cordless 3/8 impact I use to get them out. You can feel/hear the resistance with it and just work It back and forth until it spins free.

Impact it , as much time you have spent you could have already pulled the head lol. I'd almost bet $100 it will come right out with impact. Cordless might be better since you can feel more than with air.

Hit it with some candle wax when it is hot. Let the wax wick in and solidify.

I tried hitting it for about 1-2min straight with freeze-off (glow plug). Wouldn't move. Tried warming up the head around it with my small butane torch, then hit the GP again with freeze-off, didn't move. Heated the GP itself for quite sometime, then hit it with freeze-off, and got a small budge out of it. Im throwing in the towel for tonight. I plugged in the block heater for over night...atleast it might have some heat in it in the morning.

BTW, I dont have a dewalt 3/8 impact here, but I do have a porter cable. It won't budge the GP in either direction.. Man I hope I get it out.

I bet if you could get your hands on some aerokroil that would loosen it up
