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

'99 996, 6sp, coupe, 76k miles. Just bought the car and sorting out the issues (that I knew about before buying ) I suspected an RMS issue, but while under the car last night I was able to see that the oil seems be be originating from the top part of the motor and coming down the front left side (front=forward and left=drivers side correct?) The right side in the same spot is dry. If I shine a light under the intake, I can also see some oil there too. I searched with various keywords but didn't come up with anything that addressed this area specifically. Any ideas?

POST 2Original post

could be AOS (air / oil separator) top rear area of motor. Pete

POST 4Original post

Spark plug tubes also seem to be pretty common as well on these.

POST 5 / ORIGINAL POSTEROriginal post

I forgot I'd bought an index finger sized camera that connects to my PC a few years back. Hopefully I can use it to confirm the AOS or something else. Thanks for the direction.

POST 6 / ORIGINAL POSTEROriginal post

Looks like a compromised AOS...

POST 7Original post

How exactly did you get that image? I've had a small leak, bought a new AOS from pelican, I've wondered if that's really the leak. Would love to get a similar image of the top of my engine. Thanks!

POST 8 / ORIGINAL POSTEROriginal post

This wasn't done using my endoscope, but a std. camera. Jacked up the car from the left rear jack pad about 18" and crawled underneath with my feet out the back (after setting a jackstand - of course ) My head was under the inner CV joint looking up and back toward what is the front of the motor. HTH.

POST 9Original post

Wow, you're AOS is split! What a mess. Have fun with that.

POST 10Original post

That is a great pic Steveu812! We have an informative DIY tech article on the AOS subject for your review here: AOS Tech Article - 996 Mark / Pelican Parts

POST 11Original post

OMG! Thats dirty. Great Pelican info as usual. Cant wait to replace mine. Looks like a great experience!
