I'm probably just going to take it to a shop to either drill it out or find a way to remove it... just over it. This thing has to have been fucked from the factory.

Carbon on the end threads... I always try to use an impact and a 5.5 sided O2 sensor socket. Cheap autozone 5 sided O2 sensor sockets and a pry bar is almost guaranteed to strip them. You get what you pay for here.

Try soaking the threads in a carbon cleaner if you were able to break it free that 1/4 turn.
Why do people just post what they are thinking? Without thinking.
