My colbalt has pressure coming out of the oil fill tube on 2007 Chevrolet Cobalt SS

I was wondering if this problem could be a plugged PVC valve or piston blow by?

Possible but normal to have some! How much does yours have, oil blowing out?
It has some blowing out , but it hasen't blown any seals yet that I can see. It's used about a quart an 1/2 of oil since last oil change.
