Oil Leak: Engine (with pictures)

[joee76]

So, I was changing my air filter when i noticed a decent amount of, it appears, oil on the engine hose (sorry, not sure what you call those lol)

Here are some pics.

Can anyone take a guess as to what this is from ?

Interesting. Thanks for your reply. I guess I should take it into the shop before the CEL comes on.

if it is found to be the AOS, there are lots of discussion and DIY info on replacing AOS. I had it replaced at local Porsche dealer.
there seems to be two AOS's . one which is the latest and the second unit is "motorsport" flavor... more heavy duty??
can someone chime in here with more details.

i did not realize this and had it replaced with standard one. you may want to consider asking for the heavy duty flavor $$$$$$?
good luck

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.

Some good pictures of the problems, shame about the lack of information or possible causes tho, and what is that large rubber 20cm diameter hose called, Ive looked for it on pelican parts and cant find it
