so after getting a code 46 for whole 6 months.
now my o2 sensor finally goes out (no signal at all)
last night i was going to take it out with a O2 sensor socket but striped the whole thing and now there`s no mother ------- way that i can remove it...
any idea?
or does anyone has a D16 OEM 4-2-1 exhaust manifold (just the top piece, with a REMOVEABLE O2 sensor )

 

you just stripped the nut right? what i usually do is get some vicegrips.... and a mallot... tighten the vicegrips on the sensor... douse it with wd40... and start whacking awaywith the mallot.... eventually it will break loose... or you will hit yorself... real good...

Have fun...

 

yep did the same thing last week....paid 20 bucks cdn for it to end up stripping it. Then tried a vice grip and that stripped it even more lol. So had to get a new O2.

 

turn the car on and let it heat that header bright red then give it a good wack, never take bolts off your exhaust or o2 sensors with handtools cold, you will strip it every time.

 

i tried it both hot and cold and still don`t work.
i was using a 3 feet breaker bar, pushed it as much as i can, but after a while the dam o2 socket start to flex and stripped it...
will tried it one more time today with a freaking hammer.

 

my bro had the same problem, excpet with the drain plug...what we did was spray some penetraiting lube on it...let it sit for a while and use some "vice grips" and it eventually came free...the bolt was over-tightened and stripped

 

Last effort on one I had was breaking the top off, drilling a hole in the middle and increasing the drill bit in size. Once the walls were thin, used a chisle and hammer and it collapsed. It was a bitch, but it worked and the threads on the mani were still good. That would be the last option.

 

finally have to replace the whole manifold.
for some reason just by replacing the o2 sensor with a new one, the car pulls a LOT harder...(THANKS Albert )

 

don't u guys mean you rounded the o2 sensor nut.. stripping is reserved for threads.

Doesn't anyone just use a torch and heat up the area then turn it? Yeah I know sometimes you're still fucked, then you have to break out the fabrication tools.

 

go out and buy a gator grip and a breaker bar, works every time, but u'll have to saw off most of the sensor.
