Air needs to "flow" through the engine for the PCV valve (located behind the intake manifold) to work. If I'm understanding your setup right the valve cover is vented but the PCV valve is stuck closed because there is no vacuum to open it.

Here are some options:

1a)Run a hose from the valve cover to the ground
1b)Pull the intake manifold, pop out the PCV valve, cut the bottom off carefully, remove guts, re-install valve body (its now open all the time because you removed the guts) and run hose to ground, close off intake manifold port (Sporadic did this on his first turbo build, pictures in that thread)

Or you could setup a catch can: (Must be vented!)

2a) Run hose from valve cover to catch can
2b) Gut the PCV valve (same as above), run hose to catch can
2c) Throw that little filter on the top of the catch can so air can escape and the nasty stuff stays in the catch can

I think that would help your oil issues, plus the balance shaft delete for more oil capacity.
