I'm trying to change all the plugs, plug sleeves and seals on our 2.7L, 2000 Boxster and I'm having a problem with one of my plugs. When I tried to take it out, it was difficult to turn. I was able to make about 5 revolutions and then it got tighter. I'm afraid to turn any harder for fear of snapping the plug off at the base. I tried to tighten it back in, but it's very tight that way as well so I have the same fear of snapping it off at the base.
It wasn't difficult when I put it in a year or two ago so it wasn't stripped and I don't have any trouble with the other five so I don't have a clue as to what could cause this problem.
Has anyone experienced this and/or have any suggestions to get it out? It's really freaking me out because I really can't afford to be without the car right now.
Thanks!
