I was wondering if this problem could be a plugged PVC valve or piston blow by?
My colbalt has pressure coming out of the oil fill tube on 2007 Chevrolet Cobalt SS
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.
