let me first say that getting an oxygen sensor off is straight ridiculous.

took me four hours to get the old one off. i have a wsp y pipe.
yeah i used PB blaster and all that bull****, not a ****ing thing.

i can bench 350 and it took me every ounce of strength and frustration in my body to get that thing to move, after 4 ****ing hours.

so i get it off. cream my pants. guess what.

CANT PUT THE ****ING NEW ONE IN. screw and screw and screw and it wont thread. the old one wont even thread back in. what the **** do i do.

 

Thread stripped, you need a new bung. Happened to me.

 

I don't know about wsp pipes. Do the threads look ok?? Will it not go in becasue it is a diffenet thread? I am sure you checked all this but I have overlooked small stuff in the midst of being fustrated

 

jesus christ. well what do i do.

 

Go to an exhaust shop and ask them to weld on a new bung.

Mine was worse than yours, threads came off the bung and the o2sensor

 

this is horse****. how much is that gonna cost me. cant i just ****ing glue it in or some ****. haha

can i drive it? it sounds like a freaking gun going off.

 

Yeah you can drive it. Prob 20 bucks or so.

 

thanks for the info. i checked out the threads. they look pretty good. i think the shop im taking it to mon for other stuff can prob jsut use a threading tool to fix em up.

 

Yeah you might be able to retap it.

 

who put the y pipe on. whoever it was overtighten the o2 sensor that or the cross threaded it. thats why u couldn't get it off. it should never be that hard.
i'm a very skinny and weak person. i can probaly bench 100lbs top. I have a little bit of trouble with o2's but with a 3 foot breaker bar i'm god.

 

seannish,i see you are in Philly, if nothing succeds you can bring it by my shop monday and I'll see about rethreading it for ya,free of charge for fellow orger,as long as i can do it. Let me know,

 

next time heat the pipe up first, works everytime

 

that some exact thing happened to me two days ago!!! haha i got a pretty nice fix for ya... go to your local pep boys... grap a spark plug tapper (7 bucks)... i believe thats what they call it... its for if you strip out or cross thread the spark plug... guess what... its the same exact threading thats on the o2 sensor.... so re-tap the whole... then file down the buggered o2 sensor threads and make a new starting thread on the o2 sensor... still took me a while to get it in correctly but it worked perfect and no leaks!

 

i bench like 80 and got mine off

 

a nice long cresent crench made short work of an o2 sensor. Heat is another good tactic

 

80 ?

 

its called a helicoil

 

i can bench 200 and im only 115lbs and i got mine off. i woudlnt say easily, but with **** loads of penetrating fluid elbow grease and some swearing it came off. I used a 24" breaker bar to get it off, and i was on a hoist.

 

I had my dad take mine off I think. Hehehehe I don't bench.

 

i bench press my maxima then put the jack stands on. Better than using a lousy jack.

 

^^^^^Hahahah!^^^^^

 

I don't use stands I just hold mine up and work on it with the other hand!!!

 

yo thanks man. where in philly are you at? my car is gonna be at a local shop tomorrow because i wanted them to check the fuel pressure. i would defly be interested in tryin to stop by, im havn a **** load of problems with my max...and seeing as that you own a garage you might be able to help me out in diagnosing.
so just holla back and lemme know where youre at.

 

OH! we are talking about ONE REP MAX? if thats the case put me at like 100. hahahah.
no **** though...haha

 

***, i can bench my maxima and my xterra WHILE changing the 02 sensors

 

dude your swole

 

i can bench about 250 and it took me 30 min to replace all 3 sensors.

 

anti seize is your friend

 

3 ft breaker bar

 

or 3 bowls of wheaties

 

Ahh bro I'm sorry,I should specified I have a motorcycle shop but I figured I could tap the thread for ya but as for other probs,sorry. But if you have a bike I could be more of a help... I actually dont have a "good" mechanic around here,as I try to do most of the stuff myself with alot of help from this forum. There is one guy who has done some small work and is very reasonable and reliable. He is on Hunting Park between Germantown Ave and Broad Street...hes very reputable around here and prices are decent but like I said...never went to him for diagnostics or anything. Oh yea,I'm on Braod street between Hunting Park and Erie Ave. The little streets are Pike and Luzerne

 

I also put in a WSP and the O2s are not hard to come off.
Btw, muscle does not even come close in comparison to the right tools...

 

open ended 7/8" wrench, and hammer, and it will come out REAL QUICK.

for next time, of course.

 

i did have a 7/8 open ended.

what i did was put that on...put a wrench through the other end, and pushed with my foot. the car was only up about 7 inches so i didnt hav emuch room.

i should be getting it back from teh shop today, ill let you guys know what eem says.

 

I called a shop near me and they are going to charge 50 bucks to relocate the sensor. But I am in a different situation then you are. My sensor is hangning like 4 inches off the ground on the b-pipe.
