Like DSP mentions, I can't see/feel any belt connected to the air pump's frontside. Hence, do I need to block off that open orifice, as seen in my 2nd and 3rd pictures?

What's the practical consequence (functionally) of not running the air pump? Obviously it's not connected/running. I certainly don't feel any detriment to the running of the car/motor.

Also, what's the practical consequence of having a disconnected O2 sensor? The car's been running with that thing dangling apart, and I wouldn't have noticed it unless for monkeying around the engine compartment.
