YOU WANT THE VACUUM ! SUCKING VACUUM IS GOOD... SUCKING FROM THE OIL FILL HOLE IS GOOD...... OIL CATCH? SHOULD BE A SEALED ENGINE..

On vehicles with an external Crank Case Valve, CCV, the valve should be replaced. On BMW E60 with the N52 Engine, this is external. On some BMW's the CCV Valve is integrated into the valve cover. In this case the valve cover would need to be replaced.
