How hard is the o2 sensor screwed on there?
 

Jebus, how hard is this thing on there. It feels like I'm about to break my wrench trying to get it off. You guys using a 20mm right? Any tips on getting this thing off? Why would this thing be trq'ed so tight, I don't understand.

i would spray some WD-40 or PB Blaster on their and let it soak if its that hard to get out. Mabey just pull your skirt up a little :P

slip like a 4ft pipe on the end of a pipe wrench and some thrust or pb blaster. i was able to get both of my o2's out that way

They didnt invent the O2 Sensor socket for nothing. ::) just get the one that is 1/2 socket and use a breaker bar and that O2 sensor should be out in no time.

The best way is going to be to get some leverage on that beotch just make sure you soaked it in some PB ----. Otherwise you may be better off just replacing the sensor as well.

yah they invented it to make money off it. this is HMT remember? pipe wrench worked great, channel locks work great to get it on and off whenever i need to do something that involves removing the dp
