72 Dart 360 PVC valve issues

Another side note not related to your PCV issues, but is nonetheless very important. Your throttle pressure (kickdown) linkage is adjusted very poorly. The throttle pin on the carburetor should be at the rear most of the slot in the linkage so that as soon as the throttle is opened, it begins to push the kickdown linkage back. As it is now, the transmission is not getting proper line pressure when it should be. That will eventually end the life of your transmission if it's not already damaged it.
