Got the Wagner PCV valve and Moroso air-
oil separator in:
 
Couple of things I encountered with my particular set-up.  First, as I was tuning the PCV valve, I couldn't get the vacuum to drop to zero as expected.  One of the possible causes of this is too much restriction on the air flow into the engine.  I had a pretty standard issue chrome breather on the other valve cover and, when I removed it, the vacuum dropped to zero as desired, so I ordered one of these:
Spectre Performance ExtraFlow Breather
 
The second thing I had to deal with is that my pentroof valve covers are not baffled and Wagner indicated that would likely be a problem.  They indicated a customer solved this with baffled grommets (another customer said they didn't work, so it remains to be seen).  Anyway, I picked up a set of Spectre Performance 5333 baffled grommets and with these and the new breather, the PCV valve tuned as expected.  So, if I have high 
oil consumption, I can make and install baffles in my valve covers - a couple of chrome cap nuts won't look bad. 
Paul indicates he's collecting 2 - 3 oz. per 1,000 miles.  What are the rest of you experiencing?  It'd be nice to have a benchmark to see what I encounter.
