I have done the passengers side pretty easy but while doing the drivers I threaded the 02 sensor, then snapped the housing. All that is left in is the bolt. I have been trying for the last hour to get a homemade spanner from underneath with no luck, should I just attempt to take the whole housing out - bigger socket? What size is the bigger socket? Attempt turning the car on and warming and trying again, keeping in mine its threaded so I dont know if that will help. Its stuck in there pretty good, im on my second wrench. Oh and i have been preiodically spraying it with inox (as well as my arm) every 10mins or so.
yeah you should remove the larger piece that the o2 sits in.... makes it a tiny bit easier......if youve threaded it it sounds like you might need to replace that piece anyway....good luck!!!
Yeh i just realised all i did was take the top off. I grabbed a 22mm and tried, no luck, i broke a ball joint though, twisted it. I tried heating and still no luck, I didnt heat to opperating temp tho... I am not sure If I should - its really stuck there, what an afternoon I've had.
If you can't get the o2 out of the adapter/housing, then try taking out the adapter with the o2 still inside, then get it out later. Its a 1-1/4 " socket. Go from above will be easier than from underneath. Goodluck
