While I was changing my spark plugs this past weekend I accidently put my knee on top of this part that sits on top of the blower. Its that plastic knob that sticks out and it capped off with a rubber plug. Right now the plastic knob is held on by some tape lol. I'm looking at gmpartsdirect.com at the boost bypass valve, their pic does not include the black round part that bolts right on top of the blower (the plastic tube that has the rubber plug on it is attached to this part)
Its right below and a little to the right of the PCV valve.
A rubber hose from the boot bypass valve connects right to it.
I'm going to have to unbolt the thing and replace it. Thanks.
