Im confused on the flow direction of hose. Seem to go to intake on turbo and intake on manifold so which way, they seem to both suck
Well at idle I removed hose and there was suction from the intake connection on manifold
UNTIL that turbo spools up and forces positive pressure through.
Then the valve in the cover closes and vacuum is provided from the intake side of the turbo (the air box vent) in the Cruze.

Having a suction would suggest that there is no PCV functionality and that port is used to simply equalize pressure vs relieving it. BUT, just because you got suction when you took the tube off doesn't mean it's actually sucking in. If there is a valve in the tube at the turbo end then the suction is just from the motor and the valve prevents anything from actually being sucked in. PCV's are 1-way valve going out of the motor.
Ok I get it under boost it flows to turbo hence the oil residue I have at the turbo intake.
I am new to turbo engines. Do you need a Catch Can? I am not planning on doing anything other than driving my car.

U dont NEED one but oil will find its way into your cylinders. Its a safety device. If you are tuned then it would be a good idea but i recommend waiting for me to work out the kinks.
