Default Help! O2 sensor stripped and seized

Lon story short, my o2 sensor is so seized I stripped it trying to remove it.

Any suggestions? Pretty sure I damaged it in the process so plugging it back in won't help lol.

Tried applying Loctite freeze and release.... But with it stripped the only tool I can think of to grip it is vise grips :s

okay so are you trying to get the old one out ? .. if so then you may as well get the big *** vice grips on her and let her have it. if the O2 sensor is on the cat part and you really cant get it then you could take the whole piece off and take it over to a muffler shop and let them have at it . Worse case is they may leave it and drill a hole and weld on a new bung next to it for your new sensor.

I'll post pics when I get inside.... This *insert expletive here* isn't moving. I've never attached vice grips so hard on something and seen them spin like this!

A shop might be able to weld onto the steel (rest of the sensor I destroyed so only part left is steel) and use the welded on lever arm to rotate it....

Lol... Sry I meant the vice grips spun not the sensor.

Is it bad to drive the car say, 80km without the O2 sensor?

If the pipe wrench doesn't get it, you can try cutting a notch into the sensor with a Dremel and then use a large flat blade screwdriver and a big hammer to bang it loose (lefty loosey). Sometimes a sharp impact is what is needed to break it loose.

oh wow that cut looks totally photoshopped ..

Jonathan i think you just learned the first 2 real world lessons of engineering

1. if it aint broke dont fix it
2. No good deed goes unpunished.

Hahaha... It actually seemed to run better today without it, so I think Henry was right about the old one being no good.

Tonight is round 2: heat and pipe wrench!

Heat-a blue wrench. Heart the female threads on the exhaust until red hot. Then, work the vice grips or pipe wrench.

I cannot fathom working on exhaust parts that are decades old without a torch. Every garage should have one.

Thx Ed, the heat is helping. Torch it, work it with pipe wrench/vice grips, repeat!

It's turning bit by bit, but there may be nothing left of it by the time it's out!
