Default What did I break?

I'm trying to replace my O2 sensor and put leverage on the wrong line and broke the line. whoops. Anyways, what did I break? See the attached picture.

Yes, those are vice grips on the O2 sensor. That mother is on there. Originally tried that special socket for the O2 sensor, but when I got enough leverage the socket opened up ever so slightly causing the socket and nut to strip out in one small turn. Isn't it awesome? Any recommendations on getting that sucker off would be greatly appreciated also. I'm obviously having some trouble finding a spot to get enough leverage on those vice grips.

I'll post why I'm changing the O2 sensor in another post. I don't even know for sure if it is going to fix the problem and I need some input.

looks like the heater control valve, vacuum open its when heat is desired in the cab, letting hot fluids in to the heater core....

coat that 02 threads by the manifold with pb blast penetrating lube before u drive it a couple times and get it nice and hot so it fully penetrates. Doing that for a day or 2 should help.

Heat the holy hell, and I do mean holy hell outta the O2 sensor bung and use the vice grips to get it out. Let it cool before installing the new one.
