So, you f-ed up your bung-hole, huh?
Maybe some TP will fix it.
Sorry Tony, couldn't resist.

How about if I used some of that exhaust paste that hardens when it dries?

If you put the threads of the thread chaser that came with your specialty sockets next to your O2 sensor, do they match up, pitch wise, to the O2 sensor?
How did the thread chaser feel going in and out of the bung? Was it snug or did it feel like it would pop as well?

The threads seemed to match up. The chaser was snug enough to not feel like it was gonna come out.

Seems like the threads were hosed from the removal, like Scottydoggs said. You can see the amount of material on the old O2. Only thing besides welding a new bung would be maybe a helicoil. And I’m not sure how that would work on an exhaust. Maybe .. maybe as a temporary measure..?

Yeah, I got the old O2 and saw that.
I'm not sure how a helicoil would work out with an O2. I don't know why the thread chaser felt so snug if the threads were messed up.
I was thinking---How about if I used some of that exhaust paste that hardens when it dries? Put that in the threads of the bung. Think that'll work?
If you guys remember--this was one of my fears--stripping out the bung or tearing the metal. See--this Hoe hates me. That's why I was dragging my feet with the repair--I KNEW something was gonna happen! Never easy with this thing. Funny--while running I unplugged the O2 and it never set a code.
So what do you guys think if that paste?

If you’re thinking of using the paste, I’d just take it to a shop and have them weld in a new bung. It can’t be too expensive.

Tony, If you go the paste/putty route, I would consider JB Weld High Heat epoxy. It can be tapped once it cures.

It’s made to be tapped and hold a fastener.
I know you were afraid if this happening, but at the end of the day, you had a choice between keeping a bad O2 sensor in your vehicle or risking damaging the bung removing it so you can get a new one installed. This is easily able to be recovered from. As mentioned, before I resort to using putty, I would call around and see what an exhaust shop would charge to replace the bung. This happens to lots of people, and you may be surprised at how little it will cost you.

Take it to the exhaust shop and get a new bung welded on. Better to fix it the right way now, than to fight it again. Also, while you’re there, have them swap the other o2 for a new one. Guessing these are both the same age and if I were a betting man, the lifespan is about the same. I couldn’t imagine it’d cost over $100 to get both bungs replaced. Make sure to use anti seize on the threads. You spent more time trying to guess the popping problem than you did on the o2. If this is the problem, it’ll be worth it to fix it right.
