I had an exhaust turbine wheel break off and i need help on 02 remove

[silver bullit]

So my exhaust compressor wheel broke off. WTF It was a clean break off where the back off the wheel sits against the housing and where it seals the internals off. I noticed that i had oil in radiator and had a pungent oder comming from oil almost like the evap of coolant in motor. I thought that maybe head gaskit went, oil was milky comming off the vent case breather, oil in coolant, white/black smoke from exhaust, and my when i took the hose off the crankcase or the oil it would smoke like a steam vent. I was going to do a boost leak test and comp test but i wanted to swap turbo cause the 14b TD05h had about a qaurter inch .25 shaft play. I wish i had a cam this thing is toast!

Later found out that this was do to to the rubber gaskit inbetween the intake hose and turbo compresser outlet being sucked into the wheel at WOT @ 22Lbs of boost. That was the loudest sound i had ever heard of a turbo being ripped to peices. It was missing a few blades but the two quarts of oil in my intercooler thanks to the oil lines from the valve cover filtered out most of the metal chunks and large rubber chunks. I had some of the metal shaving (more like glitter) and small rubber chunks go into intake due to the traces of whats left in intake and bov. When that happened the exhaust wheel did break it must have broke with such force it broke the o2 sensor, which then stopped working and know runing to much fuel melted the sensor to a round ball that goes into the o2 housing and left metal lines from it and metal shaving in my down pipe and whats left of the cat.

Is it because the wheel had so much shaft play that the seals between the shaft, coolant and oil in the turbo became weak and gave allowing oil to mix and coolant to mix? is that the reason i had oil mix coolant?
Now that i have the o2 off i am trying to get the sensor out its allmost like its melted and welded itself shut. So how do i get that off? Ive soaked it in pb blaster, broke a couple of wrenches, stripped some other ones and still nothing, any ideas to get it off. I dont want to torch it and destroy the o2 housing.

It might just be easier and cheaper to pick up a new O2 housing.

Hey, Keep PB blasting it. What kind of wrenches have you broke? You need some drop forged wrenches. Do you have an 02 sensor socket? I would put that over it, with a really thick breaker bar, and a good extension pipe. I dont think your going to ruin your cast iron 02 housing with the torch, so use that as your last resort, try heating up the area around the sensor, on the housing. You should be able toget it out. If you can't, let me know, I'm in leesburg right now(about 45 minutes from you) and I have my old 1g 02 housing, I'd give you for a couple bucks. I could try to give you a hand getting it off as well if you need it

Broke a dollar store special, broke the open end off a stanley, and a craftsman, and few other ones are stripped now. I want this o2 because its off a 2g and is ported, and the 1g i have the o2 senser is melted to metal. Thanks for the advice maybe i should buy the open dump o2 housing now.
