o2 sensor

[takaaco]

anyone have any tricks to get this dam thing out?

without blowing a bunch of money on the sensor tool

put penatrating oil on it and still will not move , just asking before i strip the thing beyond repair.

ok, this is my first post in the e30 section, i think, so it might as well be a usefull one:

1.disconnect the O2 sensor electrical connector

2.slide a 22m(7.8) boxed end wrench ovet the electrical connector and wiring and remove the O2 sensor by turning it counter clockwise

Well I have used an adjustable wrench to pull mine out, I just carefully adjusted it while it was over the sensor. It really isnt that hard to take out its just being carefull you dont strip it. Hope this helps...

I had worries about stripping the o2 sensor, b/c on my '84 318i i can't see the darn thing and cannot reach it, except from top down. I took a long barrel 22mm socket. i cut the wire on the sensor side the length of my replacement universal bosch wire, curled the wire up, and everything fit in the socket. since the socket covers the entire bolt i didn't have any worries about stripping the sucker. and using socket wrench made it a lot easier and i didn't have to see what i was doing to take it off.

i coiled up the wire portion of the new o2 sensor and reversed what i did. i spliced the wire to the longer wire that goes to the ecu and voila, o2 sensor repaired.

Get the correct size socket and beat the shit out of it. They are a bitch to get out. Oxidation is a muther.
