Found a link for you btw https://ls1tech.com/forums/showthrea...light=air+pump
NOw that I think about it does have power going to it so I it must be a "motor".
Well searched and I was wrong, anyway learn something everyday.

Its electric... I can go out to the garage and take a picture of it for you sitting in my cabinet of spare parts. No belts attached... origionally mounted behind the driver headlight under the chassis above the plastic splash sheild. Not in the engine bay really.
EDIT: guess i had the thread open too long.. didnt see that you found it was electric

I think any oil laden vapors would destroy the thing in short order. It wasn't intended to do anything but push a little extra air at certain times during warmup. Sucking oily crankcase vapors would kill it.
I think the dude above was getting confused with the Air Conditioning compressor, which of course is driven off a short belt from the crank pulley. The AIR pump mentioned above is different, its the smog pump that blows extra air into the exhaust manifolds / header during startup to help the cats light off faster. Like it was said, it is a centrifugal blower and will not suck air if the leads were reversed.
has anyone ever done this though?
I know crankcase pressure is not a good thing but isnt the main idea to move crancase vapors, what about putting a breather on every possible valve cover spot and hooking the AIR pump to pump clean air into the crancase? I dont know how much pressure it would cause but it should do a good job of cycling the vapors. Now the problem would be the continous pump life
