I still am thinking about replacing the AOS before reinstalling the engine even though it may not be bad, depending on cost.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Is this the AOS that I read so much about? It looks like it has been blowing oil on the block for quite a while. I cleaned off the Y fitting at the top to see if I could find any cracks but didn't. It looks the oil is coming from the open tube- am I missing something? Not really sure where to start with this, so any clues would be appreciated. Thanks- John

POST 2Original post

aos on opposite corner of motro (behind drivers seat, flywheels side) that's a mess... might be aos sending excess air thru that tube... I woould sway ip, clean the motor and see what happens in time. seriously, thats dirty... why is it so oily looking behind the pulley

POST 3 / ORIGINAL POSTEROriginal post

I think this is the culprit- looks like a little check valve gone bad. I guess I will start there. I hate to install engine and find out I need an AOS. Maybe I will price it and just replace if it isn't too pricey.

POST 4Original post

Is the end of that cross member snapped in the lower right of the picture. Looks like it.

POST 5Original post

thats an over-pressure valve.... it might be doing its job. The case is not venting properly? Is your AOS area clean?

POST 6Original post

Quotes source post: 7748800

Nope, that looks perfectly normal.

POST 7 / ORIGINAL POSTEROriginal post

The AOS area looks fine and the car runs fine. I never saw this area untill I pulled the engine and trans to upgrade the IMS bearing. I have never seen one drop of oil or any fluid under my car in the 7 months I have had it. I did pull apart the connection to the crank case and the AOS line and will inspect in A.M. The fitting that the line goes into, goes into the block and there is a bolt that secures it. I was thinking of pulling it, and sealing it in case that was the leak, and tightning the bolt. I still am thinking about replacing the AOS before reinstalling the engine even though it may not be bad, depending on cost. This area is accessible, the AOS is not. Barn 996- I hope you are wrong about something else being broken! I will check.
