Hi,
It's actually a
Quasi-Dry Sump system. Traditionally a Dry Sump system consists of a Remote Holding Tank which acts to cool, de-aerate, and de-foam the Oil. Also, a secondary Return Oil Pump is used to send the circulated Oil to the Remote Tank, and there is no Sump Pan (or at least not in the traditional sense).
The Boxster lacks either of these and supplements a traditional Wet Sump with both additional capacity and an integral Oil/Air Separator. Lacking a secondary Return Pump, the Boxster instead relies on Gravity to return the Oil to the Pickup Tube(s) in the Sump. This is what defines it as a
Quasi-Dry Sump.
But there were some Oil Starvation issues in the early 996 and 986 (through '98) M96 engines during high
G maneuvering. After this MY, Porsche added additional internal baffling in the Sump to keep all of the Oil from moving to the outside of the turn and possibly away from the Pickup Tube(s). This is why the Aftermarket piece is available, but it would be redundant on an '01. BTW, DUMP the Mechanic who recommends staying with 5-6 year old Oil, his advice is unsound. Hope this helps...
Happy Motoring!... Jim'99
