It definately looks like someone jacked up the car on the oil pan.

In BMW's and Benz's it is aluminum, I dunno if all cars are the same, I thought the SVX's is also aluminum...

Nic just let it be, do not take it out, I don't think it has an effect on something in there. Just go with the necessities and then if some day you find a good one, then you will replace it.

I think he's worried about bending the oil pickup in the pan and starving his engine of oil and that would be no fun.

I would not be too worried about the oil pickup. The pan is pretty deep and having had a couple off before that dent is not as bad as it looks. I do not think there is a need to be concerned

That's no good. The 7/8 I had on ther felt just slightly loose, and the thing was so tight I'm sure if I pulled harder I would have impaled my arm on something pointy while stripping it clean.
So the wire at the top just pulls out? Mine has oily grime on it so I couldn't really see what was going on there but it seemed kinda frail so I didn't tug it.

Don't tug on it. Unpug it. It has a clip that needs to be released. Here is a few photos and info on changing the O2 sensors.
1) O2 sensor socket used with either a ratchet or a 1'' open end / box end wrench.
2) WD-40 sprayed on the threads.
3) Removal with socket and box end wrench.
4) Add lube that is provided with the O2 sensor.
5) Don't forget to unplug the O2 sensors (from below or from above)

[NikFu S.]

Seems simple enough.
I gotta say I didn't see the lube coming. Is that 100% necessary? I just want to take the things out, brush them off, and put them back in.

[dannmarr]

It's actually called Anti-seize Compound. Because of the extreme heat, I believe it prevents the O2 sensors from fusing to the pipe.
