o2 Sensor: Striped

[scottsee]

Had the day off today. First in about 11 days. Just so happens my Megan Racing muffler came in today. Good timing. I Banked on having my 3in turbo back installed today so i could get out to the track this friday and see if I could beat my 14.08 ET. All I had to do was replace the o2 suds with smaller bolts, and mount up the DP, and Mitkee was going to make a 3in catback and stick on my Megan muffler for $125.

I spent a shit load of time trying to get the cock-sucking o2 sensor out of the o2 housing! I got so frustrated with it decided to take the o2 housing off. I drained my colant (colant line runs right ontop of one of the 4 bolts) and somehoow got all 4 bolts off. I put the o2 housing with the o2 sensor still in it in a vice. I did the best i could not to strip the o2 sensor, but after 2 hours, wd-40, bolt buster spray, rubber mallet, and a breaker bar I called it quits. I'm convinced the o2 sensort aint comming out unless i cut it off and drill it out. I do not understand how to get this o2 sensor out!!!! Im supprised that i didnt break the damn o2 sensor.

Fuck.

The only way for me to get my megan racing dp to fit is if i take the o2 housing studs off that connect the Down Pipe to the o2 houings and replace them with smaller nuts/bolts so there will be enough clearance for the 3in diameter DP. Well, as dumb luck has it, one o2 houing stud came out when i took the DP off becasue the nut was stuck. The other stud donsn't want to budge, and i keep stripping the threads tying to get it off!. I'm pretty sure im going to have to drill that stud out of the housing. Just do has happens its the one on the o2 sensor side. I'm sore, and flat out tired of lying on my back on the concreat. I was really hoping to get that 3in installed today! Oh well.

Anyone have any idea's on thie 02 sensor. I've go no idea how to get it off!

<edit cleaned it up a little. I was sore & tired when i wrote this.

Not quite sure what you are talking about. Are you having a problem removing the o2 sensor from the housing or the housing from the turbo?

Took the o2 housing off.

I can not get the o2 sensor out of the o2 housing.

wow. That was relatively easy compared to getting the housing off. If I was you I would try vice grips or wrench get some kind of thick pipe(maybe two or three feet long) and stick it on the end of the wrench/vice grips and use that as a larger breaker bar. that is what I had to do with my brakes. So give that a try. It'll give you alot more torque than a breaker bar normally would because you will be able to lean your whole body on the bar.

try putting it on the groud, securing the wrench, and busting it with ur heel/bottom of ur foot, usually that works with o2 sensors, if not that, gl with whatever way u find works

I've tryed breaker bars, i've tryed pounding a hammer on my 3 foot breaker bars, I've done my best. All i've done is compleatly stip the o2 sensor. I haven't the slightest clue what to do about it. when i mean stripped, i mean circular.

Absolute worst case senerio you could cut the wires and use a deep well socket and impact that little slut off. (thats assuming you have air tools)

[scottsee]

I think i might have to. but its rounded off somthing good. i might have to pound a smaller socket into the sensor just to have any luck.

I just dont understand. I must have done somthing wrong. there is no reasion for it to be this hard. they dont make diffrent size o2 sockets do they? I bought a Power Built universal 7/8 & 22mm o2 sensor socket from Schucks autoparts. but all it did was round the edges of the sensor.

If you can't get that to work.

Vice grips and a piece of tubing as a breaker bar


and worse case senario. buy a new o2 sensor from autozone. I had to buy one yesterday because the one I used for my rear o2 sensor was to messed up to put back on. The new one screwed right on

but a new o2 sensor is like 94 dollars

[ez1286]

Do you have a welder? If it's too striped to get anything else on you could weld a bolt to the top of it and impact off the bolt. I can't imagine why it would be so hard to get off.

I never got a chance to put any reall force on the o2 sensor. Before i could pull as hard as i could on the breaker bar it would start rounding the edges. The metal soft!

No I was not going the wrong direction

well get one of those craftsman lock tight sockets from sears. that should do the trick

[scottsee]

I think your right. The only way its coming off is if i cut the wires, and use somthing to get it off.

Your best bet is to use a plumbers "monkey wrench." It is made to put massive torque on completely round pipes, so no matter how "rounded" the sensor is, that will get it out. The hard part will be keeping the housing from turning

To get that stud out, drilling is usually the way to get it done. Done it a million times. Drill that bastard out until there isnt enough material left to push outward against the threads.
