You have a direct vacuum leak from the dipstick tube not being closed off--air is being pulled through the crankcase through the dipstick tube and on back through the ccv thats not hooked up anymore
Once you plug off the hose connection there at the dipstick tube , you will be in good shape.
I really like what your system looks like now that you have added the parts on I suggested. Question--does your distribution unit have to ports for hook up. I notice that you have only one port used (same as mine)--what did you use to plug the other port--I used a vacuum cap that I bought from Advance Auto that worked great--just seein what you have used there. As for using washers and stuff inside the distribution uniot--I gave that idea up when I started using the PVC valve system--Where did you get the oil catch can your using and I might need the part# of the valve your using also--I made mine up and it looks pretty good, but I'm likeing what you have there even better
Hope that helps
