Service bulletin PIP4543B

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

PIP5197F2018-05-21. Service bulletin. This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that have excessive oil consumption, blue smoke from the exhaust, or a Malfunction Indicator Lamp. Technician should inspect the PVC orifice for leaking oil or drawing a vacuum at idle. If the PCV orifice external port is leaking oil or vacuum, replace the camshaft cover assembly. Technician will inspect for a missing intake manifold Non Return Valve that may have damaged the PCV orifice diaphragm. Check for the return valve if it is not visible use a long cotton swab to wipe any excess oil from the valve to validate. If the non return valve is still not visible, then intake manifold removal for inspection is required to validate. When the valve is present reinstall the intake manifold.
