The 3.6 Pentastar engines have pretty terrible PCV systems. I bet your intake is filled with oil. If you want to test this, just get a J&L oil catch can and hook it up in a few minutes, and check it after a couple of hundred miles. If it fills up fast, the PCV valve is your problem. Even when they work, they let a lot of oil into the intake manifold. You have nothing to loose if you go this route, because an oil catch can is preventative maintenance anyway. Don't worry about oil grade/brand/etc. These engines aren't hard on oil, but they have a bad PCV design. Good luck!
