This document describes replacing the Air Oil Separator(AOS) for a 987.2 The design of the part that attaches to the motor casing is slightly different that other Porsche AOS. There are two round stubs that have o-rings on them, so no more hose clamps. Otherwise, it seems very similar to previous AOS designs. Two bolts on the AOS, E10 torque 13Nm(9.5 ftlb.) Here are the steps to replace the AOS: 1) Remove the top access hatch.
