Glow plug removal
Here's two ways I've used to avoid pulling the head(s). Nothing is a sure thing...
There's a special tool that's a split nut -- open the nut and put it on the plug threads, insert spacer under the nut, turn the plug with a socket and hopefully use the threads to jack it out. Without this tool, you run out of threads before the tip comes up the hole. This tool cleverly adds female threads so turning the plug continues forcing it out of the head. Anyway, it's OTC part number 6005.
The other way I've done it was to improvise a slide hammer. Small vice grips on the plug, bailing wire on the vice grips, piece of pipe over the bailing wire (slide hammer part), and a socket extension attached to the end of the bailing wire for the pipe to strike against. Sort of proud of this method.
In any case, lots of penetrating oil. Some unsavory words directed at the plug manufacturer also seemed to help.
Best of luck, hope this helps.
... But since I tried replacing those plugs and found the swollen heads wanted to separate from the threaded part and I now have two cylinders I need to repair for sure and am hoping to find a way to do it without taking the head off if I can since I was planning a larger truck project for next year which may include a complete rebuild.
Any ideas folks? I guess I should have just kept a can of ether in the truck just in case but it's too late now. Is it possible to block the precup's outlet somehow and knock the tip into it then use a magnet to drag it out the injector hole? Until I can do something to the engine, I won't run it any further than onto the gooseneck and borrow my brother's truck to pull it into a shed so I don't freeze my ball bearings off.
Any suggestions would be appreciated, then I can go back to driving the favorite truck in my fleet. And then I can implement some heater options I have been working on.
