Anyone ever rig an O2 sensor on a carbed y-pipe?

Featured Replies

My FI y-pipe is all dented from playing horse with the Jeeps in Bangs Canyon.

 

I've got a good y-pipe from my carbed parts car, if there was some way I could use it that would be convienient.

Take the spare Y-pipe down to a local Muffler Shop. They can install O2 fitting for you.

You can also buy a weld in bung for O2 sensors. Then you torch out a hole, weld in the bung, and your O2 sensor will screw in.

 

Time for some real skid plates out there on the rocks! :brow:

weld in bung

you said bung:lol:

 

Joel try Trade center salvage out passed the mall. I got them to sell me and EA81 Y pipe a few years ago.

There's only SPFI car in the all the junkyards in Junction! It's down offa S 5th... It's a 90 4x4 with a bad 3AT, but the y-pipe was rotted.

 

Aparently the guys there used to race a Hatch in Tough-Truck competitions! They got a kick outa the wagon.

 

Anyway, a local muffler shop said $35 to do the job. More than twice what I paid to have my diff welded, but not bad.

 

BTW, anyone know what the thread pitch is for our 02 sensors?

a universal one from napa screwed in, so its about the most common o2 thread pitch out there. other than that... im useless =]

i'm looking to get a carbed y pipe from the marketplace forum from XNRG. with a welded in O2 bung will i be good to go on my MPFI XT? other than the O2 sensor the carbed vs. MPFI y pipes are identical?

It seems that way,at least for SPFI. A local muffler shop put in my bung for $15.

Almost all oxygen sensors have M18x1.5 threads.

 

So do 18mm spark plugs, actually. You can get 18mm "spark plug non-foulers" from the auto parts store that can be easily made into weld-on-able oxygen sensor bungs with a little cutting. They're basically little spark plug extension dealies:

I did it!!!

I did the SPFI swap so I needed one... went to napa got the o2 and bung... used a hole saw and cut a bung hole, then used a socket to keep the bung in place while I welded it on...... works good

i think i have one on my carb'd ea81 88 gl hatch. there's a wire going into some sort of fitting on the cat. do some years have them and some not?

cool thanks guys.....now i just need to find an EA82 y pipe of any kind.
