  Summary

  This Preliminary Information communication provides information to the technician that some vehicles may have rattle, tick, or knock type noise. If there are any drivability concerns they should be addressed prior to the following diagnostic progression. Technician will take a sound file or video with sound of the noise prior to dis-assembly. Technician may find this noise hard to isolate to one area in the engine. There are four different steps to take to diagnosis the concern. Technician will perform injector diagnosis to ensure there are no leaking injectors causing a noise due to excessive fuel in any one cylinder. Replace any out of specification injectors the reevaluate for the noise. Technician will remove the intake manifold and visually inspect for excessive carbon on the intake valve stems and top of the valve causing noise. If carbon is present then follow the latest version of PIP5029 to clean the valves or replace heads as needed. Technician will remove the cam cover of the affected bank (both if needed) to inspect for soft or spongy stationary hydraulic lash adjusters. Push down on the rocker end at the stationary hydraulic lash adjusters to test for soft or spongy. If soft or spongy stationary hydraulic lash adjusters are found, carefully remove the affected head and inspect the oil passage below the head gasket for debris. If debris is found, inspect the camshaft caps for wear or discoloration due to lack of oil. During inspection if wear or discoloration is found then replace the cylinder head assembly with camshafts. If there is no wear or discoloration, clean the oil passages and replace the head gasket. Technician will use chassis ears or a stethoscope; listen to the right and left side of the engine. Once the noise is isolated or if unable to isolate, remove the piston and rod assemblies from the affected bank(s) to inspect for either; a loose rod bushing in the rod, or a loose wrist pin in the bushing. If this is found, replacing the piston an

  Summary

  This Preliminary Information communication provides information to the technician some vehicles may have a drive motor generator, battery control module and cooling fan may become inoperative due to low system voltage. There may have been a charging system message, battery warning lamp or service hybrid system message displayed and may have Diagnostic Trouble Code P0C32 and or P0A7E. If the voltage level drops to a predetermined level approximately 9 direct current volts use Global Diagnostic System 2 to command the battery pack cooling fan motor on to make sure it operates. If the fan does not operate it will need to be replaced. Technician may need to run the vehicle through several drive cycles to ensure that there is not another root cause for the low voltage condition. Technician will need to reprogram the generator control module.

Verify the fuel pressure using a scan tool the actual and desired fuel pressures are very close to the same. If contamination is found in the tank then completely flush the fuel system and add e-10 fuel. Also remove the high pressure fuel pump inlet line from both ends. Using regulated air down to about 60 pounds per square inch or lower, blow through the inlet side of this pipe / hose. Inspect for restriction in the check valve built into this hose. If restricted then replace the pipe run a tank of premium fuel through the vehicle and reevaluate the concern.

  Summary

  This Preliminary Information communication provides information to the technician that some vehicles may have a Service Engine Soon lamp, engine misfire on cylinder 1, 4, 6, or 7 and/or tick noise. Technician will follow service information diagnosis first. If service information diagnosis does not isolate the cause of this concern perform a cylinder deactivation active fuel management system compression test in service information. If the running compression of the misfiring cylinder stays below 25 Pounds per Square Inch regardless of the active fuel management solenoid being commanded on or off, an active fuel management lifter is mechanically collapsed/stuck or unlocking as soon as the engine is started. Replace all active fuel management lifters, and all plastic lifter guides. Also perform the cylinder deactivation active fuel management Valve Lifter Oil Manifold Diagnosis and Testing in Service Information. If it isolates a concern with the Valve Lifter Oil Manifold, replace it and reevaluate the concern. The active fuel management lifters can also be monitored for proper operation by carefully inspecting the cylinder 1, 4, 6, and 7 rockers and valves while cranking or briefly and safely running the engine with the valve covers removed. If the valve or valves of an active fuel management cylinder stop moving while doing this test, the active fuel management lifter is causing the concern. For 2008-2009 Full Size Truck/SUV or a 2007-2009 Chevrolet Tahoe with the Police Package reprogram the Engine Control Module. On the 2008-2009 Pontiac G8, 2010-2011 Camaro, and 2007-2010 Full Size Trucks with active fuel management, also determine if the active fuel management pressure relief valve shield that is listed in the latest version of 10-06-01-008 has ever been installed. On passenger cars with the LS4 engine, determine if the updated oil pan gasket that is listed in the latest version of 11-06-01-007 has been installed.
