Throttle Body & Vavle Cover Question
 

Doing a swap and have a few questions - The two hoses that come out the pass side of the TB, Top one goes behind the motor and attaches to the brake booster? Correct?

Where does the lower hose go? Pass side valve cover grommet?

Also, What hose goes into the pass side breather hole on the valve cover and where does it come from?

That top spout connects to the passenger side breather. Red circles are what need to be matched up.Attachment 331790Attachment 331791

The lower spout on the TB is for coolant, it connects to the heater control valve.

EDIT: Christ I'm losing it. Even just looking at the picture, that lower spout is vacuum.

Just a note, the pass side isn't a PCV valve, just a plastic elbow.

Re: Throttle Body & Vavle Cover Question
 

8Mike9 is correct that the passenger side is just the breather not the PCV. The PCV plugs into a barbed fitting just behind the drivers side runners on the lower intake. The brake booster connects to a barbed fitting on the drivers side back corner of the upper plenum.

As for the bottom port it is supposed to connect to the EVAP canister.

This may help

For a Camaro, the evap can is on the driver's side. You should have a hose that loops a 180* turn to go under the TB to a hard plastic line to reach the evap can.
