How Do I Stop Oil From Entering Air Cleaner Area From Crankcase Breather Tube?

I have a 2003 Chevrolet Cavaleir 2.3 engine and oil is being sucked up from valve cover breather tube into air cleaner intake tube.

    Replace the P.C.V. Valve.  It sounds like it is stuck open.  Take it off the valve cover and the hose and shake it.  It should "rattle". If it does or doesn't, I would replace it.
