I have an 08 Vert and am pulling the OE headers, cats, and catbacks off. The downstream O2 sensor was in VERY tight, got about a quarter turn on it and then it seized. Hit is with some penetrating oil, let it sit for a while. Came back and rounded off one side of the bolt face, but finally got it out. The threads in middle of the O2 sensor were destroyed. I am sure the **** is not in much better shape although I have not gotten a peek inside yet.
All stock car, owned by a dealership in MN, so I doubt it has ever been touched according to the service records.
Is this common?
