I was told it was the AOS but the problem was fixed with the different engine in the new Cayman S.

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Hopefully someone has experienced this problem as well and can lend their sage advice. After a morning of lapping at Highplains Raceway outside of Denver, my 2000 Carerra 4 emits white smoke from the exhaust with larger amounts on restart in the paddock. Most of the articles I have read have said that the AOS is the culprit. After returning from the track the problem subsides. I have not checked the oil consumption as I change after every track session. The only other time I have seen smoke from the exhaust is after a really high turn through a cloverleaf freeway on ramp. The only 2 constant variables I can see are the high G turns and the hig rev of the engine. Any experiences similar to this and your outcomes and advice would be greatly appreciated.

POST 2Original post

With the 3.4L it could be a few things. I have heard of the Air Oil Separator (AOS) causing the issue, but it could be other things. Have you modified the engine for oil starvation? X51 oil pan, oil spacer kit? The 3.4 in high g turns have the tendency to "let go" under these conditions. x51 oil pan oil spacer - Flat 6 Innovations with oil pick-up spacer We also have the Motorsports Air Oil Separator (AOS) for your car too. My:2cents:.... I would suggest having a Technician look at the car to make sure there is not some underlying problem. Thanks Aaron www.SuncoastParts.com [phone removed] [email removed]

POST 3Original post

I had the same issue with a Cayman S - no smoking and little or no oil consumption on the road but at Road America DE had a cloud of smoke after engine restart. I was told it was the AOS but the problem was fixed with the different engine in the new Cayman S.

POST 4Original post

I have had same problem on hot days when tracking long and hard. Some have found idling for 5-10 minutes before shutdown has helped - seems to help me except on hottest days. I have had 3rd radiator to help cool oil and Motorsport VOS recommended. Have you found any solution for your issue?

POST 5Original post

Take a read through this thread - lots of info and some solutions... http://www.planet-9.com/cayman-boxster-complaints/20457-severe-smoke.html brad

POST 6Original post

During DE's at Mid-Ohio , all of the Caymans leave the track after their session and take a little cooling- off trip up to the main gate, then back to the padock. Doing this prevents the oil smoke on the next restart of the engine.

POST 7Original post

Thanks to both of you. Driving a bit at moderate rpms after the session may burn off oil that probably is getting through the AOS/VOS better than the idling for 5-10 min. that I have tried. Next track day, tomorrow, I'll try driving around after sessions before shutdown.

POST 8Original post

It is very normal for you to see white smoke. All flat engines do that, remember your piston is sleeping on its side not like in normal engines. Check your AOS as it is the main culprit I had this problem at the track, i took it lightly and ended without an engine on my 03 C2. Also the dealer always warns that every 5000km the car will loose approx 1L of oil. To be safe as mentioned before check the AOS and try to avoid very warm weather at the track.
