Hello All I just bought a 1977 240D and am trying to change the glow plugs. But they are stuck. Anyone have any ideas? I can unscrew them but the centers don't turn and the outside part comes off leaving the center part still in the hole and wont budge. Please help. The Chiltons manuel is no help



I did do a search and found where 1 person used pliers to pull them out. I tryed that with no luck at all zero movment. the car has been setting for 6 years Thank you.
