Bryan;

Yes, you've put your finger on something that can really help. An air/oil
separator can save bearings! A good dry-sump tank has its oil return lines
plumbed in at an angle so that the oil swirls around the inside of the top
of the tank; bubbles of air are broken up and separated from the oil. Check
out a Peterson oil tank to see how it's done.

Of course, many of the advantages of a dry-siump system are negated if one's
wet-sump pan is VERY deep. If the pan is deep enough, the crank is far
enough above the oil level that it doesn't churn the oil into a froth. An
engine usually is mounted low in a car so going to a very deep pan isn't
possible.

Neil,

I guess I missed it. I didn't see anyone mention what I see as a big 
advantage
of dry sump. A good dry sump SYSTEM should minimize aeration of the oil.
After a 30 second 8,000 RPM oil system test run, the Mobil1 in my
Kawasaki looked like it had been in a blender. (I had a clear sight
tube on the crank case & oil pan) I see dry sump and crank case evacuation
as the best way to get as much air out of the oil as possible.

NOTE: I do not have personal first hand experience with this so I may
be completely full of it.

Bryan
