So I was replacing my glow plugs in a Ford 1720 when carbon build up prevented the new ones from going in. I thought using a gun cleaning brush would clean things up then...snap about an inch is stuck inside the bottom of the glow plug housing and I have tried to suck it out with a vacuum, tried to hook dental floss on it to pull it out...the fish hook wouldn't fit down the tube and I have tried working it out with a slim metal dental pick. It is stuck in there good! Open to any an all suggestions. I don't know if I pulled the injector in front of it whether that would provide any better access. Can I operate without it? Ideas???
