Positive crankcase ventilation

I also have the M/E Wagner adjustable valve (and followed the instructions)... works great.
Even with a random PCV stuck in the grommet, the first one I found at Autozone that fit, there was only about a teaspoon of oil in the oil separator after 500 miles. So I removed it - just one more source of leaks. Baffles in the valve covers is the important part. That and good rings so blowby is minimized.
