[RESOLVED] Stripped o2 sensor problems

[DeNoZZo]

So I start today planning on an easy project after school. So I get home from school and start replacing my o2 sensor. I literally though this would take maybe 30 minutes max. I go to take the o2 sensor out of the housing. All I had was a standard size wrench that would fit pretty tight. So I went ahead and used it. I doused it with pb blaster, and started wrenching.... Nothing, it wont move at all and was starting to round the corners. So I go to autozone and pick up a 20mm wrench. Get home and it wont fit. Go back to autozone and pick up a 21mm. Nope. Back to autozone. This time, I get a special socket for taking an o2 sensor out. I get back, and it fits good. I get impatient and clip the wires at the base because they were in the way. And I figured I wouldn't have to use them again. This socket is what really stripped the corners of the sensor. Once it was getting pretty bad. I switch over to vice grips. You guessed it, it didn't budge. So now I bust out the monkey wrench. Had it stuck on there real good, but could not get it to move for the life of me, or my friend. I finally decide to take my o2 housing off so I can get to it at a better angle. I decided to give up for the night at 11:00. I still have to get the housing off, and to get that off, I need to get the manifold off, and then the turbo will be bolted to nothing.... and so on...
I am so frustrated right now it's not even funny. What I thought to be a 30 minute job has turned into a 6hr + job. And now I'm going to have to bum a ride to school and work tomorrow off my friends/parents. Idiot who replaced it last probably didn't use anti sieze .

What do you guys suggest? If I can't get it out with the housing off the car, I don't know what im gonna do. Maybe order a new one? But where?

You said the housing is out of the car? What about clamping down on the o2 sensor w/ a vice or some vice grips at least...

o2 sensors never go as planned, wait... that goes for everything else also. haha.

no, the housing isn't off yet.

Use a good pair of vice grips on it and clamp down on it good. You may need to use something as a cheater bar for more leverage on it. Don't be afraid to clamp down on the sensor hard, it already looks pretty messed up, the harder you clamp the less likely it will be for the vice grips to turn on the o2 sensor.

heat up the o2 housing around the sensor, causes the o2 housing metal to expand a little bit, and should make it easier to come out!! don't know if you tried that yet.

Heat up the o2 housing around the sensor and use a pipe wrench.

heated with a sodering torch and nothing


EDIT for future references- Took it to a shop and they got it off with a real torch.
