Help: o2 Sensor will NOT come out

i can not get this thing out. Tried everything, PB blaster, WD 40, Warming the car up and trying to take it out after i turn it off.... but no luck...And the o2 is whats causing my car to run so terribly. Anone have this problem? How can i get this thing out...everytime i put my full strength into truning the socket wrench, the O2 puller slips on the O2, and i dont want to round it off....?????

Well, if i beat you when i was stock, what would happen now?

I've never used an offical O2 puller so I don't know what that is. I used a 6 point deep socket, and cut the wires right at the sensor so the socket would fit over it. Some propane torch heat, and actually tightening it a bit, then loosening it over and over got it off. The ultimate cauase was years of carbon baked on the threads. The 12 point deep socket I started with would not grab well enough.

what size is close to a 7/8" deep socket....maybe ill try that idea

o2 sockets that i seen are just a deep socket with a portion of the side slit so that the o2 wire can still remain. The ones i've seen tend to be quite weak, due to this design which gives less of a grip on the sensor itself.

O2 sensor sockets suck. Why not use the closed end of a 7/8" combination wrench? If need be, you can attach the closed end of another wrench (a 1" wrench should work) to the open end of the 7/8's one for leverage.

When you put the new o2 sensor in put some Anti-seize on the threads.

Use a pipe wrench. It will either turn the O2 sensor out or turn your motor sideways. Its the only thing I could find to get the EGR tube off, should work like a charm on the O2 sensor.

I found that a quick, hard jolt like hitting the (well seated) box wrench with a hammer broke mine loose just fine. That's also how I removed the EGR fitting from the E6.

Prior to doing that I soaked the fitting with WD-40 and warmed it up a bit by running the engine for a few minutes.

Alternatively, if you can get an impact gun in there it'll most likely come right out.

Good luck.

Hopefully you get this before...

IMHO, you need to have the exhaust warm/hot *before* attempting removal. I have pulled a number of them from older cars, and when the manifolds/pipes were cold.... ended up stripping out threads (especially when I have done most of the techniques mentioned above and nothing moved).

Good Luck

Specifically, how do you know you need an 02? I been off line for a few days so if you already answered this in a prior post, my apologies, I'm working my way down the list
