Cause	Correction
Incorrect oil filter without anti-drainback feature	Install the correct oil filter.
Incorrect oil viscosity	Drain the engine oil and replace with the correct viscosity oil.
High stationary hydraulic lash adjuster (SHLA), valve lifter, leak down rate	Replace the SHLAs, valve lifters, as required.
Worn crankshaft thrust bearing	Inspect the thrust bearing and crankshaft. Repair or replace as required.
Damaged or faulty oil filter by-pass valve	Inspect the oil filter by-pass valve for proper operation. Repair or replace as required.
Malfunctioning camshaft position actuators - improper oil viscosity or contamination.	Isolate the noise to a specific camshaft position actuator. Disconnect the electrical connector on the camshaft position actuator solenoid valves and start the vehicle. If noise is gone, repeat procedure to limit to an individual actuator. Refer to Camshaft Position Actuator Replacement - Bank 1 , or Camshaft Position Actuator Replacement - Bank 2 .
