I have a Ford Focus 2009 SE 4-Door (2nd generation) at 180 000 km. The maintenance schedule said I need to replace the PCV Valve. I went to the Ford dealer to buy the part but they told me my model doesn't have a valve and there's nothing for me to do.
When I search online I see videos of people replacing the valve on their focus and even this site that has a part number https://www.rockauto.com/en/catalog/ford,2009,focus,2.0l+l4,1443428,exhaust+&+emission,pcv+(positive+crankcase+ventilation)+valve,5052
Does my car have a PCV valve and does it need replacing? Can I trust the part from that website will work?
