Some customers may comment on an engine tick noise. The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter. Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi).
The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil.
Inspect the 0-ring seal and replace as necessary. Use the applicable part number listed below. Refer to the Engine Mechanical sub-section of the appropriate Service Manual.
Parts are currently available from GMSP0.
For vehicles repaired under warranty, use the table shown.
Installation Note: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems
these have roller lifters,,,he cam shouldnt wear in these..the o-ring listed above is just one 99cent o-ring..it gos on the pick up..if it is bad,the lifters would have low oil presure and cause them to rattle...it is not likely for the cam and the lifters to be bad...please understand i cant see it......this wouldnt cause a 0300 code....this is a missfire code..i will give you a chart on this
CONDITIONS FOR SETTING THE DTC
ACTION TAKEN WHEN THE DTC SETS The PCM illuminates the Malfunction Indicator Lamp (MIL) under the following conditions:
CONDITIONS FOR CLEARING THE MIL/DTC IMPORTANT: If the last failure was during a non-typical driving condition, the MIL may remain ON longer than the three ignition cycles. Review the Freeze Frame or Failure Records for the last failure conditions.
DIAGNOSTIC AIDS IMPORTANT: Remove any debris from the PCM connector surfaces before servicing the PCM. Inspect the PCM connector gaskets when diagnosing or replacing the PCM. Ensure that the gaskets are installed correctly. The gaskets prevent water intrusion into the PCM.
