Timing chain rattle on vehicle start-up.

Possible causes:

Timing chain could be stretched or may have loosened.

Repair steps:

  • Connect the DrivePro device and then read out the DTC for the engine. If the code P1336 is set and the DPF light is flashing while the engine is running, you should check timing chain as described below
  • Next, remove the valve cover. Once this has been removed, the timing chain, camshaft gears and valve train will be exposed
  • Now, check the tension on the timing chain. Check the timing chain for any slack by pushing on the chain on the tension side. You should not be able to feel any slack
  • If any slack is felt then the timing chain kit will need to be replaced. It is also advisable to replace the oil pump chain at the same time
