How to Service the PCV Valve on Ford Flex?

Service of the Positive Crankcase Ventilation (PCV) valve begins with removing the crankcase ventilation tube from its connection to the PCV valve. One must replace an extracted PCV valve because exposure to the valve cover may damage its locking mechanism. First apply engine oil to the O-ring seal before removing the PCV valve by turning it counterclockwise from the valve cover and discard the old valve. Finish the installation by executing the opposite procedure while confirming the new PCV valve sits firmly within its place.
