72 Dart 360 PVC valve issues

From what you described....
  • I wonder what kind of vacuum you have coming from the carb on the side?
  • Is the hose too big for the PVC valve fitting and leaking around it? Try a hose clamp to see if that helps
  • I mean, we could be talking blow-by
Lets not bring up Blow-by just yet lol.

I'll get a clamp tomorrow and see what happens. Like i said when i take the valve off and stick just the hose end (i know its not a good thing) it stops.But with the valve in it doesnt do much of anything. Is there a after market valve that might be better to use than just the plastic ones?
