I can't get my fuckin o2 sensor out of my KA's manifold! It is beginning to round off, too. Should I just destroy it in the process of replacing it, or is there some way that is better?

If it's shot, just get it out.

If you have a crappy socket, or wrench, set around, just hammer on the next size down and get a breaker bar on it somehow... that should break it loose.

I don't know where to get it either... but some stuff called "Release-All" I tried once works awesome. Frees anything that's seized.

pb blaster is some good shit.

daryl337 · 08-20-2007, 12:00 PM

pb blaster is actually one of the best you can use. Rock out with it.

LA_phantom_240 · 08-20-2007, 12:51 PM

This thing sucks. I can't get it out. I don't have a 22mm box end wrench and I don't wanna have to resort to anything rash. I guess I just gotta wait for the o2 sensor socket to come in.

Just go to sears, home depot or a hardware store and buy a set. They are a good tool to have.

LA_phantom_240 · 08-20-2007, 01:15 PM

I have no cash, just money in paypal. Oh well, a few more days of running pig rich isn't so bad.

Adam496 · 08-20-2007, 01:26 PM

Since you are replacing it just use pb and locking pliers.

LA_phantom_240 · 08-20-2007, 01:27 PM

Nah. Then getting the new one in would be a problem. I'm just waiting for my tool to come in. Use the right tool for the job the first time and be done with it.

if you heat around the o2 sensor it will come out eazy

22mm? O2 sensor is 7/8" SAE.

MyLevinGTZ · 08-20-2007, 05:51 PM

7/8"= 22.2250 mm

i think you'll be fine with the 22mm ><

if it's rounding off, you'll need to use vice grips anyways.

LA_phantom_240 · 08-20-2007, 10:17 PM

I only rounded off one corner. I'm running richer every day, and while idling and working in my trunk I noticed a small black puff of smoke.

Pig rich. Smells like a lawnmower. It sucks. This socket needs to get here ASAP.

get a pipe wrench and pb, thats how i got my egr off and it worked great. o2 sensors are cheap anyways so destroy it.
