The air oil separator or AOS is a common failure part that leads to white smoke coming out of the exhaust when you first start your car. Fortunately, it’s a relatively easy and cheap repair.
In addition to the white smoke, symptoms may include a check engine light with codes P1128 and P1130. This is how I solved the problem on my 2000 Porsche Boxster S. For my Boxster, this was part number 99610702304.

hey burner found a quick easy way..start by taking off tire..get long extension and swivel for 10mm..take two bolts out first then all hoses come off easy..took 45 min
Thank you i will go over the fuel lines and thw fuel pump, the air lines i think i went by all of them
yes i did checked them all ,when i spay start fluid to the air filter the car doed start for a moment and turns off again so o need its something with the fuel not sure yet
hi i tried to take out the hoses that goes to the oil separator and put the back in till they stap on but still no success to start the car ,so i guess its a different reason that the car crank but not start cant understand why
i checked the hose that going out of the oil separator, disconnected them and conected from new bit no success to start the engine
thank you so much again
thank you, i will definitely check it in the morning again ,i felt that the tube that goes from the oil separator to the truttle body wasn't so tight ,but didn't tought it might be it
hi ,i did change the oil separator to origin variation which bought from ebay amd from some resom my car didn't start since then,i do have a crank but it's doesn't start
tried to put some starter fluid and it started just for a second and turns of right away
checked the fluid pump relay and it looks working fine but no success to start the car,
any idea what it can be the reason
thanks
