How to Service the PCV Valve on Lincoln MKZ?

The servicing of the Positive Crankcase Ventilation (PCV) valve should start by disconnecting the battery ground cable together with the electrical connector attached to the valve. Move on to detach the PCV hose from the valve. The installation of a fresh PCV valve becomes necessary because taking the valve out of the valve cover can harm its locking mechanism. There are two requirements for new valve installation: apply clean engine oil to the O-ring seal and verify correct positioning of the electrical connector versus the wiring harness connection. Incorrect placement demands complete valve removal. The rotation of the PCV valve counterclockwise allows its removal before disposal. The installation procedure requires following the opposite steps of removal.
