May or may not be related, but there was a recall on RX-8s for oil warning lights coming on at speeds over 80 MPH.  It wasn't really low, just foamy.  Don't know what the fix was but they did not change the size or shape of the oil pan.

I wonder whether a chain slipping through the oil would really foam it up that badly. The oil in the rotors certainly get churned into a foamy state.  The old connection rod splash rod would really foam the oil as it "beat" the oil several hundred times a minute - but I'll bet if anything the chain will just created a small turbulent area around it but not wide spread as it smoothly slips through the oil.   Just speculation, of course, never seen a chain running through oil. 
 
Hi Ed,
 
Good point...  As usual, I'm probably worrying about nothing.  I know that the RV-3 chain ran in the oil during climbs, because I had a really hard leak to find.  I could run the engine on the ground, and it would never leak, but after a flight, there would be oil.  Eventually, after slopping grey sealer everywhere (sorry Rich), I found the right place to put it. 
 
If you look at a 3rd gen REW front cover, you'll see that they added an extra bolt near the top of the cover.  The spot where they added the bolt used to be a fairly long unsupported area, and it just happens to be right where the oil chain slings oil at a high velocity.  That's where it leaked of course.  
 
Rusty (wondering if I can get away with one oil drain)
