Well doing a little maintenance on the V70 R, 2004 6spd, 170k. Replaced one of the coils that went bad 2 weeks ago and put in a new plug. Didn't have the time to replace the others at the time so I was going to do it this afternoon. 3 of the 4 plugs came out with too much trouble. I don't recall it I put anti-seize on them when I last changed them but I recall them being a bear to get out. The plug next to the upper engine mount is so hard to turn, not sure if this is #1 or #5. I usually use my "T" handle to remove spark plugs but had to switch to my 8" ratchet to barely move it. I would loose a little and then tighten like you would tap a hole. I worked on it for about an hour slowly backing it our but threw in the towel it just kept getting harder and harder. Put everything back together and I'm off for some 4th july events. Any suggestions how to help it come out?
spark plugs stuck but good

How did u remove the broke plug?
If you can get all the porcelain out, you can try a big easy out. That probably won’t work. So off with the head to a machine shop. Ask me how I know.
The answer to your question is Seafoam the intake and let it soak just like when you do a treatment. But after it soaks a half hour then remove the plugs. They will come out without damaging the block.
I took some out of an xc70 with original plugs at 215,000 miles.. Had to soak them, all the difference in the world. Spray from top all you want it does nothing, its sealed to combustion pressure. You have to get it inside.
Good luck! It will work.
