Chances are you have what is called blow by. That is when the rings wear out in the engine and allow compressed air to enter the engine block. Then, oil and air is forced through the PCV and into the air box. Check the PCV and make sure it is good. Also, start the engine and remove the oil cap to see if a lot of pressure comes out.
