Hello everyone I got a code regarding a bad 6 cylinder glow plug two Thursdays ago I brought it in the garage and began to replace the # six plug it was a little tough at first but worked it out. It was spinning on the top "freely" just would not come out. Since then over a week ago I go to work then work on removing it To 1 in the morning, last night I removed the left side fuel rail. I made a fitting that fits over the top of the plug with a slide hammer. It will not budge I bought a video scope and it's will not move a bit. With all the force Why won't the 4mm small piece of metal pop through. 2015 Bighorn 3.0 ecodisel. Any help on what I can do would be much appreciated thanks
