Where is the PCV valve on a 6.4 powerstroke?

On a 6.4 Powerstroke diesel engine, the PCV (Positive Crankcase Ventilation) valve is located on the driver's side valve cover. It is typically integrated into the valve cover assembly and connects to the intake manifold. To access it, you may need to remove components like the intake tube or other obstructions for better visibility and reach.
