The circular plastic top with the green dot.. The piping underneath it bolts to the metal rail that runs along the sid of the motor.. There is one in the front and the back of the motor. My local auto parts stores dont have a clue what it is... :angel

Its got something to do with special emissions equipment that only came on 2000 GAs IIRC.

Yeup, that's the AIR crap from the 2000's

Errr... I was searching around for a gasket since both units were all grimed up.. I cleaned them up but the gaskets were toast.. Since the pump is only on for a minute at startup I am going to buy some head gasket material and replace the stock material.. I was going nuts since no one knew what it was.. What did the 2001 GA's do in CA to get legal if they removed all this AIR crap???

Yeah. That's an AIR check valve for whichever manifold its closest to.

For minute there it looked like the PCV vacuum pump.
