Catch Can instead of the AOS...anyone tried it yet?! - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Still in testing and will be for a good while. When creating such an outside the box part I must cover every base and attain data for "argument" purposes later when some know it all pops up to question why we are omitting what "Porsche designed".

What about the Motorsports version of the AOS (part number 996.107.926.00)? While this is quite a bit more expensive than the standard replacements I have read that it solves the issues with oil getting past the stock AOS on hard left hand turns on the track.

I've gone through about 3 AOS. I am currently running the Porsche Motorsport AOS but I fear it's not really doing the job. My boxster is boosted with a Turbowerx kit. The PM AOS was a genuine PITA to hook up and I probably didn't get it right. Any tips on how to install a catch can? What to plug up etc..

:dance: I have been using a catch can approach to solve my consistant AOS problems. It works well but I am finding that on the track the first quart of oil is picked up by the catch can after that without replacing the oil it works fine. As a result I am running one quart low..

My catch can is located in the engine compartment between the engine and the transmission. I also placed a drain tube that extends below the aluminium sheet panel with a shut off value for ease in draining the Catch Can.
