Porsche Boxster Air / Oil Separator Replacement - 986 / 987 (1997-08) - Pelican Parts Technical ArticleThis emissions device can cause a lot of problems. The good news is that it's easily replaceable, as shown in this tech article.www.pelicanparts.com
It can still be caused by running the oil level high and not letting it idle for a bit after parking.
My 996 blew smoke all the time with the oil full and almost never with the oil at the "add" line.
I hope this fix the smoke. Right now, oil level is 2/3 full.
