Hey,

So, the weather has been really bad here, and I have been real busy with school, so the volvo has been sitting in the garage. Since I am still living at home (just my mom and me with 3 other cars I can drive) nothing nice, but they work so I have not been super motivated...but I want my baby back.
So, I bolted the OBX on two days ago and the rear o2 is like miles off. How do you extend the o2 on a 99? Can you splice it and just make it longer or is it super funky and I have to pay big bucks from volvo and get an extension.

Also, any tips for getting the left side bolt off of the intake manifold?
I am doing the PCV and am stuck on that bolt. I tried going in from the bottom, but I do not have enough extensions.

Thanks guys...I really want to get it up and going again:)

buy more extensions... and you can splice the o2 sensor with more wire to make it longer.

my friend who put mine on had ones long enough, she used to me a mechanic, I would suggest measuring how long you need, then if no one here can give you a link or a hand in finding one, just go to your volvo guy if you have one or goggle it.

idk if the 3/8ths is too small or not, but that was the longest I coud find online.

If you are talking about the intake bolt that is below the t-stat housing, you can get to it from the top. I use a 1/4" extension about 15" long and a 10mm swivel socket.

If you looking at it from the front of the car, it the last bolt of the far left of the intake right next to the radiator pump hose thing.

Harbor Freight sells a very useful set of wobble extensions: http://www.harborfre...temnumber=31203

Alright.
So, I got my buddy coming over on friday and we are going to finish the PCV job and do the o2. He seems to think I could just splice it and make it longer.
Anyone know what gauge of wire I would need to do so?

[T5wagon1717]

Anyone have anything on this
I am hooking up with my friend on friday and would like to be able to get this done.

not sure on the wiring gauge i think used 18 gauge when i extended mine. also if you are running catless i suggest you get an 02 spacer so you won't throw a code for the rear O2, one can easily be fabbed from a spark plug anti fouler..

[T5wagon1717]

That I actually already did. I was running catless with my previous exhaust, so I made a spacer with a spark plug fouler. It seemed to work fine. My problem is just extenind, some people do it, but they were all 98 and older cars, and I am afraid since mine is an ME7 that it will mess something up.

[echo5625]

you should be fine.. just make sure you know which wires goes together, on mine there were 2 white wires, so i had to make sure not to mix them up. if you are unsure about it, ipd and fcp both sell o2 harness extensions

if it's the rear should be the same flat 4 pin which should work

[T5wagon1717]

Alright.
So I am sort of an idiot when it comes to wiring. I am not too worried about getting the mixed up...but use the same wire for all.(same kind of wire I mean) and you said like 18 gauge should work. Any old 18 gauge from a hardware store would work?

[T5wagon1717]

alright guys.
I know a ton of people run OBX. How did you all extend the O2 sensor???

[echo5625]

yea i used some black basic wire from the walmart, soldered the wires together.. electrical tape them up, wrapped them all together, got some of that plastic wire tucking stuff, zip tied it under the car so it wouldn't hang and hooked it up. and it worked, i know it work cause it threw my car into limp mode since i didn't have a spacer..

[T5wagon1717]

Sweet man. I will give that a shot. I already have the spacer, so I should be good to go.
How did yours work once you added a spacer?

[T5wagon1717]

So, I need some help.
One of the exhaust clamps broke, and I need another one. Kragen does not have one that would work. Anyone have one they like that would work. Its the last clamp right around the back axel of the OBX kit.
