02 sensor housing install help.

[guitarXgeek]

Hi guys, I'm in the middle of installing my 3" turbo-back exhaust with evo3 o2 sensor housing! I've got all the exhaust off except for the o2 sensor housing. The very top bolt closest to the radiator seems to be tightening back up once we start loosening it up. Why is it doing this? Crossthreaded possibly? How would we fix this?

Secondly, how the #### are you supposed to get to the bolt at the back of the o2 sensor housing, closest to the block??? There's an oil line running up to the turbo that's blocking any room to get a wrench in there. Am I supposed to take this off first? Any suggestions, comments, experience would REALLY help me.

And one last thing, I've looked in my Chiltons and searched quite a bit for the torque specs for the o2 sensor housing up to the turbine housing, and I can NOT find it. Help?

Thanks,
Matt

I Got mine off by laying on the ground and getting a ratchet and proper extension on the nut, and yes, using a "wobble" or i call it a jointed extension

Well we've decided that taking the manifold and turbo off will be the best way to do it! Also, thank you SO much, 98spydert, for that link!
