Whistling Sound when engine starts up

146 1
I have a 2014 Chevy Cruze LT and I had my co-worker who has worked on cars before have a listen since this is my first vehicle and I am one nervous nelly thinking everything is going to crap out any second :ROFLMAO:
When I started up the engine and we popped the hood she said everything sounded okay but she is wondering about a whistling sound.
Is this just normal for a Chevy or should I look into it more?

THAAAANKS GUIIIIZ, much appreciated for any clues :)

Potentially PCV related but it should throw a P0171 code with it.

Pop this cover off the engine.

Once off and the engine is running check for suction at the PCV shown in this next pic. There should be 2 small holes towards the front and back. If you have suction there then the PCV system is damaged / faulty / broken. At a bare minimum you likely need a new valve cover and possibly further PCV system repairs.
