I cant break this 02 Sensor loose, i havea 7/8ths o2 socket which doesnt seem to do the trick. already soaked in PB blaster, I pulled the starter out to get more leverage from the bottom, still the thing wont budge. Tried angle wrenchs, still nothing...
Then tired from the top of motor with extentsions,swivels and the o2 socket.
I dont want to cut the wire just yet because if i cant get this off im screwed!

Do you think heating it up will do any harm?
Any other suggestions?

Ps. i got stock manifolds/Y pipe still on there

 

I would try to heat it by the threads on the exhaust. shud come/

 

Or try a 1/2" breaker bar.

 

From the top or bottom?

 

Where ever you can put the most body weight onto it... I had a problem breaking loose a crankshaft bolt off an Eclipse a couple weeks ago... I used a breaker bar with an old long bumper jack slipped on the end for leverage and finally broke it loose... Sucks not having air tools... So you have to improvise... But heating it may be an easier solution.

 

I would try heating it if you're replacing it. I have broken bolts and damaged threads using breaker bars in the past. I only use them if I have to.

 

k, im gonna heat it then...i already got the new 02's, i just want to break this sucker loose
