PCV-Vac-Advance routing

You want the VA hooked to the port on the metering block. That’s timed vacuum. The easier ways to tell if it’s timed or full vacuum is the full vacuum port will always be UNDER the throttle blades and the timed vacuum will be above the throttle blades. And, you can’t just look where the port is. You have to see where it comes out.

The PCV should be hooked to the 3/8 full vacuum port at the back at the carb.
