N192210230	2019-08-19. Service bulletin. N192210230 - Special Coverage - Some 2015-2016 Chevrolet Cruze and 2015 Chevrolet Sonic vehicles equipped with a 1.4L engine may have a condition where cracks can develop in the diaphragm of the Positive Crankcase Ventilation (PCV) pressure regulator valve. This valve is a part of the engine camshaft cover. If this were to occur, excess air could be drawn into the engine intake. As a result, the engine may run rough, especially during idle, the Malfunction Indicator Light (Check Engine Light) would illuminate and a diagnostic trouble code for Fuel Trim Lean (P0171) or other airflow related DTC would set. Dealers are to replace the engine camshaft cover as necessary. The repairs will be made at no charge to the customer.

PIP5421F	2018-11-13. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may be running rough with a Malfunction Indicator Lamp on. Technician may find Diagnostic Trouble Code P0300 set. Technician will need to perform an Engine Compression Testing in Service Information. If excessive leakage to the crankcase is isolated, check piston and cylinder wall condition. Technician should perform the repair per the level of damage. If the cylinder wall surface has not been compromised, only piston replacement is required.

PIP5197F	2018-05-21. 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. When the valve is not present replace the intake manifold assembly.
