Scavenging and aeration in the oil pan have been identified as a problem in the 996, 997 and Boxster models that experience high G-forces on the racetrack.
The Motorsport oil pan has the baffling concept of the X51 oil pan. It also increases the oil capacity because the pan is deeper. This pan adds close to 3/4 of quart (0.6 Liters) of oil over the original X51 pan. This allows for increased oil cooling and engine performance by preventing oil starvation and oil foaming.
The Motorsport oil pan is also designed with external cooling fins
which helps to lower the oil temperature.

Please note: This kit will not fit 996 Turbo / 996 GT2 / 996 GT3 / 997 Turbo / 997 GT2 / 997 GT3 / 997 S 3.8L

The AOS is basically a small diaphragm distillery which distills the minute amounts of oil mist in the crankcase, liquifies it and sends it back to the crankcase. The "clean" air is now sent into the air intake (after the throttle body) to be burned off by the engine.
When the AOS starts to fail it cannot separate all of the oil out of the mist and some liquid oil is sent to the air intake.
A few drops of oil is enough to generate the GREAT SMOKE BOMB for which our cars are famous for.
A big smoke bomb once in a while is completely normal, due to the architecture of the flat-6 engine, which may let a drop of oil flow into one of the combustion chambers sporadically.
