Smoking Exhaust

I replaced the serpentine belt.  I replaced the boot between the air cleaner and the throttle body but forgot to tighten the hose clamps.  Drove the car over 100 miles and it started to smoke.  Tighten the hose clamps and the smoke went away.  A couple of days later the smoke is back.

i think I might need to replace the air/oli separator.  Maybe it just needs to be drained.

Thank you for responding to my HELP issue.

As far as I know, the Primary AOS on the 997.1 3.8 is not serviceable by draining.

Have you checked your crankcase vacuum? Either with a manometer or the oil filler cap removal resistance method?

How old is the AOS? If not original, is it genuine Porsche?

Any squealing, screeching noises?

Do you park on an incline?

Is the smoke persistent or only at start up?

Have not checked the crank case vacuum.  Will take it to dealer.

The AOS is original.

No squealing noises.

Yes, it is parked on an incline.

It is there on start up and then goes away.  It then comes back on deacceleration when the car is warmed up.

Thank you for your reply.
