O2 Sensor Seized, help!
 

Ok i bought a std manifold yesterday at the wreckers, and i can't get the old oxygen sensor off. It is TOTALLY STUCK on there!!!! I'v tried WD40, liquid wrench, a breaker bar, pipe wrench, and even heating it with a torch. I'm assuming the thread is not a reverse one or anything, just your normal thread right, countercloackwise to loosen(i know stupid question)I'm thinking i should just throw it away and get find another manifold at another wrecker. Any suggestions to how i can get the O2 sensor off??
Thanks alot

The O2 sensor was on there when i got it from the junkyard. The sensor is full of carbon crap, which will prob give bad readings.

hahahahaha...
I had the same problem.
I just cut of the top and drilled the thing out.
And if you damage the threads just drill a biger hole, fill it with some rod weld or something and make new threads.

I drilled out the first one i had.... the second one broke the O2 sensor socket adapter i bought.... and the third time i just got some of those vice grip pliers... tightend it to the o2 sensor.. doused the sensor with wd40... and started pounding it with a rubber mallot untill slowly but surely it started moving.

remember to use anti seize compound on it when you install it, so this wont ever happen to you again.

u try heating up around the 02 sensor. dont heat the sensor.

i use a huge adjustable wrench. if that doesnt work add a pipe. itll come out..

Hey, thanks guys! But yeah, yesterday i bought a 3 foot extension, and the dam thing still wouldn't come out. So i guess its time to drill that bitch out!
And another question for ya guys....
Theres a crack starting at the bottom flange and it goes up about 2 inches. Should i just put some of that brass coloured crack filler for headers on it? Or is it junk.....i hope not because i paid 40 bucks for the manifold. Thanks!

try and get some kroil.. its the best stuff ever made. way way better than WD40

mine were stuck on too, but i used some kroil and a huge wrench, i was able to get them out just using my feet to hold the manifold. but if you could put it on a car or in a vice it would help so much
