As can be seen from the photo, one of the downstream O2 sensor studs is messed up. I tried cleaning the threads, but I can't get my thread chaser started (M8x1.25). All the other studs are great. Any solutions here?
- Is the stud replaceable?
- Is it possible to salvage the stud with some other thread repair method/tool?

The studs are not serviced by Toyota. You buy the pipe to get them. If you can get it out a 90116-08020 might work. That number is an intake manifold stud for a 1FZ

90116-08211 may also work. I'd be inclined to try that one first. It's an exhaust manifold stud for the air injection pipes on a 93-94 1FZ.

Just wanted to close the loop.

I was able to remove the old stud thanks to the power of magnetism and Liquid Wrench:

Only replaced the damaged stud, but used new nuts.

Which toyota part number for the stud did you eventually go with? This might be a situation I find myself dealing with in the not too distant future.
The stud is part number 90126-08001
And the nut is part number 90179-08059
