Doesn't the air/oil separator simply catch the oil the engine pukes, so
the
oil doesn't end up on the belly? If that's the case, your separator
better
have a capacity of almost 4 quarts, 'cause I suspect the engine is still
gonna send the first 3.5 quarts out the breather.

Yes and no.

It constantly feeds the puked out oil back into the crankcase, so you can
run with a full crankcase instead of one that is 1/3 empty.

I'm no mechanic, but more fresh oil sounds good for my engine.
