Deep Sump Oil Pan Spacer, when is it required? - 6speedonline.com Forums

See those little rubber flaps hanging down? That's what makes the X51 oil pan unique, the flaps open & close during significant oil shifts. The force of the shifting oil closes the flap, and helps to keep oil in the center chamber for an extended amount of time. Since these flaps are not installed on most models, oil can rush out of the center chamber under extreme conditions and bam.......the oil pick-up tube has no oil. This piece has been very effective, and a great alternative to replacing an entire engine. Driving these cars to the extremes does have it's risks, but this should help to reduce that risk.
The X51 pan can be modified to fit most late model cars, there is an edge on the vertical bracket which has to be cut to clear the inner components (I have a templete with dimensions). A mechanic should be able to make the modifications with a grinder. It can be fitted on any Boxster, Cayman, or 1999+ Carrera (not required for Turbo, GT2, or GT3 models).
