I was able to get the dreaded header bolts off easily, what I am having troubles with is the o2 sensors. I was able to get 1 of the rear o2 sensors off but the front ones will not budge. I am using a 20 or 22mm open ended wrench. I have sprayed the **** out of them and given it all my strength and nothing. Any recommendations/opinions are appreciated!! lets get my x-pipe on today[&:]

you need heat....no if ands or butts...no heat... you will break it... u need to heat all around where the 02 sits in the pipe...then it will come loose

So you think I should start it up for a little bit and let it idle until it gets warm? If I throw a code doing that it will be cleared the next time I unhook the battery right?

timeformiller44

yeah unhook battery and code will be cleared but it will come back unless u fix whatever the code is

and as far as running it... if u dont have a set of torches or propane torches to heat the pipe.. go for it.. just dont burn ur *** and be careful!!!!!!!!!!!!!!

Better yet, get an O2 sensor socket. Thats what they're made for.

Just unplug the wires and work on it out from under the car. If you don't havea torchalready go to Home Depot or Lowes etc etc and get yourself a Bernz-o-Matic turbo torch head and a bottle of Mapp gas. Heat all around the bung and it should come loose, done this many times, good luck.
