The vacuum for the PCV should be isolated from any other vacuum operated accessory. Is there no manifold vacuum port on the carburator? If the one with the PCV is the only one, then you will have to use that. Another option is a carb spacer with a vacuum port. Of course this depends on what carb you have.
