About the Ultimate AOS
Design Theory
USPTO Patent # 11,326,489
The Ultimate AOS design works by taking a systematic approach to the problems associated to to the Factory AOS and correcting/improving them. The UAOS is not just an improved replacement part, it is a complete redesigned System.
The Factory AOS design is well known for failing of the flow control diaphragm, and the result is increased oil consumption, or excess smoking, and in severe cases engine hydrolock causing bent rods and cylinder damage.
When the flow control diaphragm fails in the Factory AOS, the present procedure is to replace the complete AOS. This procedure is very labor intensive due to the location of the Factory AOS, and involves hours of labor.
In the Ultimate AOS design, the flow control diaphragm regulator is moved to easy access at a location near the throttle body and can be replaced in a matter of minutes. The "Vortex" part of the air-oil-separator is left as Factory designed and drains the separated oil back to the oil sump.
As an additional design improvement, the Ultimate AOS, incorporates an Accumulator in series between the Vortex and the Flow Control Diaphragm Regulator. The Accumulator acts as a secondary air/oil separator and collects any excess oil in the crankcase vent system. Also incorporated in the Accumulator is an infra-red sensor set to activate an in-dash warning if accumulation reaches a dangerous level of about 117ml , indicating a fault in the Crankcase Vent System and allows for operator intervention before any engine damage can occur. This feature will save engines from the threat of hydrolock.
The Infra-red warning feature is Microprocessor Controlled and wired to the low coolant warning circuit, and will "slow flash" the red warning in the instrument cluster.
Professional installation is recommended.
Design Advantages
The UAOS will stop the worry of "catastrophic failure" of the engine due to hydrolock. It will also eliminate EVER haveing to replace the AOS AGAIN, which is a costly and time consuming job for most shops. Failure of M96 engines due to AOS malfunction is responsible for more engine damage than has been previously assumed. The emission legal UAOS Street Version can be ran with oil level "full", (no need to run at 1/2 qt low due to to AOS deficiency), The emission legal UAOS Street and Track Version can be ran at 1/2qt to .75qt" overfull". The non-emission legal Race only version can be ran at .75 to 1.25 qts "overfull" for oil starvation protection..( NOTE : oil level recommendations are assuming your engine is in good health by testing blow-by. Test blow-by for normal readings using this procedure in the Rennlist thread https://rennlist.com/forums/996-forum/1185646-engine-health-blow-by-test.html?highlight=blow-by+engine+health )
