What is a AOS Failure?

[sb01box]

I'm not a weekend mechanic and there are plenty of threads here for air oil separator (AOS).
i'm told that it is a larger capacity positive crankcase ventilation. Keeps the oil vapor in the crankcase while venting unwanted pressure into the intake manifold.

I did not pay attention to it till it failed. when my car's failed, a white plume of smoke 50 to 75 feet up in the air as wide as the street.

"mosquito fog" as stated by a member.

Fitting the motorsport AOS is a decent size job, it's not just plug and play. Also, the cost of the motorsport part is about 5 times the cost of the standard.

Interesting, I was wondering how oil might have gotten onto my engine:



I haven't noticed any AOS problems, so hopefully it was already replaced, only had the car for a couple months.
