air oil separator

Recommended Posts

When looking at the '05 air oil separator there are three hoses/pipes coming off of the top end of the AOS. Does anyone know where these three lines go? If you are looking at the PET diagram the hoses I am interested in are numbered 12, 5, and 13. Mine is not "stock", I am attempting to change it back to stock and don't know where to route these lines. Any help or diagrams would be greatly appreciated.

It's not stock b/c we converted it to a one way catch can rig. Using the port that I believe would be used to vent the air back into the intake manifold, we diverted that hose to a catch can mounted to the fire wall. After reading about failed AOS that push large volumes of oil into the manifold I believe I have a worn out AOS. I say that b/c after about 30 minutes of running my 1 1/2 quart catch can fills up! So I was going to replace the main AOS unit. But to make sure I didn't mess up, I wanted to change the system back to stock. Also, there are two hose ports on the top of the '05 AOS that look as if they are vacuum line hoses??? if they are I am wondering if they need to be put back on. If you can help I would appreciate some advice. If the link below works it is the PET diagram of the 996 AOS. Look at the top three hoses, these are the one in question.
