So, what do you experts make of this piece of ...!
After a lot of struggling under the car, this is what finally came out of my 'S'-pipe! Lovely, eh? Needless to say, it doesn't thread into my CEL Eliminator and the Eliminator doesn't thread into the bung .
Hope you guys don't mind if I'm having unkind thoughts towards Toyota at the moment !

I presume you're talking about replacing the 'S'-pipe bung? I'm wondering if I can run a die over that wasted sensor thread and get it good enough to use, and perhaps a tap would recover the bung. Course, I don't yet know what thread size it needs !

I used both the correct slotted hardened tool for the job and (mostly) a 22mm combination wrench direct to its base. I fought it and it fought me for a considerable period of time and effort (way more than fifteen minutes). Unfortunately, the above photo depicts my reward !

The exhaust system couldn't have been colder, the engine hadn't been run for 18+ hours. The front O2 sensor was perfectly reasonable, this one wasn't -- I have a hard time viewing this as anything other that an original Toyota screw-up.

Sorry to hear it man....

And I'm sure it was but Toyota probably wont replace it same thing happened to me and I ended up just buying a new o2.

No question, I've no doubt I've no recourse, but it's a huge ____er none-the-less ! And I should let their dealer "technicians" touch my car? FY Toyota!

OK! By grinding the destroyed thread and filing the entry to the remaining thread, I'm now able to cleanly install the sensor into the Eliminator. Can someone please tell me what tap size I need to restore the O2 bung thread?
#15
From hunting around on the net, it appears as though the correct thread spec is 18mmX1.5. It also appears the O2 bungs are normally much harder than the sensor threads and so a chaser may well be sufficient to clear it. However, since I can't even start the Eliminator into the bung, it seems unlikely I'd have any better luck with a chaser !

Picked up a chaser today and spent some quality time (???) with the 'S'-pipe trying to remove it from the car. After soaking the rear bolts with solvent, I was finally able to break them free with a breaker bar and took the following photos of the bung threads.
Looks to me pretty much like metal was poured over them ! Tried the chaser a little, but all I was doing was hurting the chaser threads. Just ordered a tap and so the car will remain dead for a few days -- thanks Toyota !

Of course, YMMV.

Bummer! I fought with mine too but in comparision mine was a cake walk. In case it helps anyone else, I soaked mine with PB Blaster and then used MAPP gas to heat and expand the s-pipe bung and a "good" closed end wrench on the O2 sensor. Mine finally broke free with all threads intact. Be sure to use a good anti-sieze compound on the threads of all O2 sensors on re-installation.
Of course, YMMV.

I'm quite certain it was cross-threaded, the three surviving threads were mostly protruding from the bung when I started, and the crushable washer wasn't tight. It was a couple or more orders of magnitude harder to turn than the front sensor.
