Maybe there's a pinched line somewhere or some blockage or some sort of plastic stopper in the CCV that isn't collecting oil vapor and shooting it back through the intake. Put an oil catch can on it, they can be made from a plastic bottle and you will see how much oil is collecting. After I sprayed my Z I had oil consumption and I installed a catch can to help take the oil passage out of the manifold.
Maybe just take it out and reinstall it.
EDIT: Did you change the hoses also? It really sounds like you have a clogged or backed up hose somewhere.
Did you say that you put stop leak in it? That's raising suspicion.
My E28 offer still stands.
