hello and thank you for contacting just answers.
the fault you have are pretty common.
You most likely have a bad breather valve. The breather valve has a one way valve that fails and causes air to leak into the crank case.
the valve is located under the engine cover. attached the the valve cover.
disconnect the hose that goes to the hose where the arrow points in the picture from the intake. Then try and breath through the valve It should only go one way if it goes both ways the its faulty. If your going to replace it your self make sure to remove the valve and bring it with you to the dealer because there are two part # XXXXX if you get the wrong one nothing will change.
