Heat shielding on crankcase breather and oil return lines
Coolant bleeder valve
Port connections from the AOS to the cylinder head and to the top of the block
The bottom of the canister is shaped like a snail which redirects positive crank pressure into the same swirl pattern produced by the 3 side ports which allows for maximum oil drainage while separating oil from the air in all of the venting ports
The backplate of the AOS features a unique coolant routing system that heats the entire AOS to the same temperature of the engine which maximizes the evaporation of any water collecting inside of the can
