Pcv Valve? Oil Sucked in Intake

Hi I have a 07 LT 2.2 cobalt I was wondering where the pcv valve is located? My car seems to be sucking up a lot of oil into the intake. Would that be a pcv valve or?

Is it a manual transmission? And if so, do you typically downshift to assist your braking?

Get a catch can. around $10 on ebay and it will prevent the oil getting to the intake without disrupting the air flow.

Check for a colapsed or split hose in the "PCV" system.

Hope this helps a bit. There is no check valve on the Cobalt.

Been trying to figure out why it's sucking up so much oil into the intake. She also had been having a tough time starting. turns over a fee times before catching or turns over acts like it is going to start then Back fires and shuts off. I replace the spark plugs and is still having a rough time starting. The first time after replacing the plugs started right up. But back to the same problem now.
