Does anyone know how to time the 2.5L TD duramax engine or have a manual which explains the procedure or know where I can find such? I messed up when trying to replace my timing belt and now the engine won't start. Any assistance would be greatly appreciated.
Sorry, beyond my knowledge. My manual says use the cam locking tool made for the job and a quick look at google suggests the cam has moved due to valve spring tension when doing the job without the locking tool(?) You could try the US Colorado forums.
