Engine Mechanical problem
2001 Cadillac DTS V8 Front Wheel Drive Automatic 90766 miles

I was changing the spark plugs out on a 32 valve northstar and the number 5 plug will not come out it was extremely tight I put alot of weight into it to break it free and then it popped now it spins left spins right and wiggles up and down. It does not tighten, does not loosen, and will not come out. Spark plug is still all together and not broken from what I can see. Do you have any suggestions of what to do other than pulling the head off? I cranked motor to see if compression would push it out and it did not work!

Try breaking ceramic ouy drilling the rest out. Buy thread repaier and Tine insert. But this is a very high skill level and not always it will work.
