Help - Oil leak on top of engine - newbie

[CJ_Boxster]

Well that clamp doesnt get any tighter than it can squeeze on its own, its a normal clamp that you remove with simple pliers. you probably cannot see the other end of the clamp that you'd grab with the pliers cause the AOS lines are blocking your sight. You can get the AOS cheaper from suncoastporsche.com

I sent you a PM about how to remove the AOS lines.

If the Oil Filler tube is the cause of the leak, the best way to seal that leak is to remove that portion and line the interior of the tube with silicone to create a seal between it and the hose it connects to, then place the clamp back on... Dont start the engine till it drys so that it can cure and you dont suck a hole though the seal because of the crankcase vacum.

See how to replace/reseal the oil filler pipe here:

FWIW, I'm nearly certain you don't have an AOS problem. It's totally normal for a Boxster to puff a little smoke on initial startup. Since your's does it very infrequently, it's normal and nothing to worry about. If you had a bad AOS, your car would puke a large volume of smoke, and continue doing it for > 10 seconds at startup.

As for the oil filler pipe, you may find that it has been sealed with a piece of worthless fabric tape at the joint where you identified the clamp. Simply seperating the two segments at that clamp and applying some grey RTV may be all you need to correct the leak. The pipes probably haven't cracked.
