Chances are you are using engine oil with a high vapor rate. The vapor, by way of the PCV valve, is being returned to the intake causing the oil on the filter. Change your filter more often or change the brand and/or grade of the oil.
Let me guess? Its a 2.5 , Rings are worn creating excessive blow by in crank case.
