he "clean belly" is just icing on the cake.
The real deal is the significant reduction in oil consumption...

After the 3rd oil change since installing the Air/oil separator it appears that oil consumption has decreased very slightly. Although I somehow wanted to see the big improvement initially, I cannot measure a significant change in oil consumption.
The way I precisely measure consumption is by counting all the oil in and
measuring all the oil that comes out at oil change plus anything added between changes usually one quart keeping oil level between 8 and 9qts.
So for me it's the clean belly and an absolutely clean engine compartment
without any leaks or seeps from anywhere.
I have measured negative crankcase pressure and I have installed a second reed valve.
The exhaust stub does coke up over time but with a second reed valve installed I feel comfortable keeping the breather tube connected to the exhaust
reed valve.
Clean out the stub every other oil change works for me and to double check I stick a bore scope up the tailpipe a couple of times between oil changes.
