Here's what you should look at:

Drain the oil and check if there are metal shavings, it is normal to find some amount of very very small metal particles, anything larger and there could be a wear problem.

GEARS: A little play when moving the pulley counter & clockwise, around .5mm-.8 would be considered normal, more play and maybe theres a bad gear.

BEARINGS: there should be almost no play if you push-pull the pulley.

Impeler: check for cracks and rubbing spots around it on the case.

Leaks: they do leak a bit sometimes, if not severe then it is ok to experience some.

SHAFT: spin it and see that the rotation of pulley and impeller are straight, shouldn't wobble.

It's probably not a good idea to buy one off of a random person when all you know about the condition of the blower is that it's a good deal.

Buying any used supercharger is a roll of the dice. Met a guy the other who found out later, that although it was supposedly "new in box" someone had put a "used" head unit in the box. Looked great in the pictures.
