If the rings and seals are good then may be this is your problem... take apart the Air box, AFM and J boot and check for oil. There should be oil residue but not alot of standing oil in this area.

If one or both O rings that seal the air/oil seperator is leaking this will cause oil to be sucked into the intake at high RPM through the hose from the air/oil seperator to the J boot. It is not clear why this happens, the air/oil seperator functions somewhat like a giant PCV valve but when the O rings start leaking it starts to function like a siphon and start sucking oil into the intake at high RPM.

Part Numbers are:
Seal 24x5 999-701-661-40
Seal 20x5 999-701-613-40

Your next steps should be:

remove intake manifold
remove oil filler tube from block
replace air/oil seperator O-rings

You may want to replace the large O ring in the oil filler cap as well (O-Ring 999-701-653-40) as that is another source of air leakage that affects the operation of the air/oil seperator.
