How to install an oxygen sensor bung on SSI?
 

I need to add an oxygen sensor to my SSI's. My current SSI's do not have the bung installed.

Does anyone have a photo that shows the proper placement? Any specific measurements would be hepful as well (i.e., xx inches from flange, etc..).

Lastly, I cannot find a weld-on bung for sale on the Pelican site. My maintenance guy at work (who tig-welds stainless all the time, says that he has what I need and he say that the bungs he has are heavier duty that what I will find out there). Any comments from the Pelican Brain Trust on this?

Thanks for any and all advice. I need to get this done for my electromotive engine management that I will be installing at the end of the month.

Second picture in my thread here shows where I put mine.
No measurements, sorry.

Bought a stainless bung on Ebay.

I have a 3.2, and just measured 9" from the center of the bung to the flange. It was installed on my SSI when I purchased the vehicle.

Perfect!

Thanks for the photos and the measurements. This is exactly what I has hoping for.

Here's one from Pelican if you want to go that route (I searched "oxygen sensor bung") -

Porsche 911 (1974-1989) - Engine Miscellaneous - Page 9

Thanks! I didn't think to look in the misc engine section. I notice that Pelican sells two models that look identical...one is $16 and one is $9. It's not a big deal but it would be interesting to know the difference (other than price). I may need to ask.

If you are just looking at the Rothsport stuff from the link, one is the Bung for $16 the other is the Plug for $9.
If you type bung into the search you also find a stainless bung from Innovate.

Perfect timing, I'm doing this as well. Thx.

I welded mine on the in-pipe for the muffler - works fine and not stainless steel.
