o2 sensor stuck like cement

[head4life]

I have had no trouble ever removing a o2 sensor with a breaker bar a o2 sensor socket and a bottle of pb blaster

it cant be THAT hard

if your not very strong use your leg power like exr33 said

heat it up with a torch...thats what i had to do first time i changed my o2...but after that first time i now soak it in pb plaster and use a wrench with a long pipe.

soak it with pb buster....

I'd try a wrench with a long as pipe over the end of it as a breaker bar, and i would use my leg/foot to push the bar while a friend holds the wrech in place with a rag so it doesnt slip off and strip. whenever i cant break a bolt loose by hand under the car, i use my leg strength

on the a1, the o2 sensor is on the manifold, not the down pipe. he would have to stand on the car to use his legs.

yeah like everyone is saying, I think when you heat up the manifold, it will allow the metal around it to expand, thus making it easier to remove. so you could just drive around and then try and take it off

what i did with mine, since i'm just replacing it anyways, i snipped the wire as close to the sensor as possible, soaked it in PB blaster, then grabbed a deep impact socket and just impacted the shit out of it till it came off

(of course, the manifold was remove from the head)

SUCCESS!!

I bought PB blaster and bomb the hell out of it. Overall I spent 2 hours on the process not including yesterday and the day before yesterday. I hammered the shit out of it too to help it loosen up. Cut the sensor in half to have more work space. After that I was happy that it loosed up and can be removed by hand. That made my day..

Here's the picture of the lil prick.




Thanks for all your help guys. I followed everybodies advices. Thank You , Thank You.
