The numbers are in!

Im not sure on how much vac it should have but it is supposed to pull between the air filter and throttle blades. Another option would be to install a catch can. Between the PCV and filter. This would trap the oil from going into the motor. Here is the first one that comes to mind. http://www.custombilletstore.com/Hemi_Oil_Catch_Can_p/20010.htm

They will typically catch about 1-2 tablespoons of oil between oil changes. You can find cheaper versions on eBay, might be eorth a look. But it's more of a band aid fix, are you running the factory windage tray/oulpan gasket? That will help too. The biggest problem though could be the piston rings. If your loosing compression to the crank case your forcing the oil vapor to go somewhere with the motor running plug the PCV line, with your thumb, wait a few seconds and remove and listen for air pressure there should be none. If so I would conside doing a leak down test, to see what cyl is leaking and start there. Is it possable the piston rings were not set up correctly on one piston or got moved durring install? And now the gaps are lined up. That would cause the pressure.
