I'll post a pic when I get home this evening. I had a Road Demon 625cfm vac. secondary carb on the motor. It had no provision for a PCV valve on it. I drilled and tapped a hole in the carb spacer for it. This is below the throttle plate where I thought it was supposed to be. The Demon was a problem from day one, so I swapped it for an Edelbrock 1405 600 cfm unit from a well running motor. This carb has a provision for the PCV, so this is where I am now connected and yes I did plug the hole in the spacer. It looks as if it is above the throttle plate but it may not be.
