thanks for the advise. will make detailed inspection today during the daytime.

looked at the engine top to bottom. no sign of external problem.
would film of oil at the bottom of the airfilter box and dripping out of the water trap point to aos malfunction?
just surprised at the amount of smoke that came out of the exhaust!

took today off from work with the thought to replace aos myself.
thinking about potential collateral damage of do it yourself work.
talked with Porsche service, he mentioned that when aos goes, it's like F1 engine blowing up. lots of smoke.
he gave me couple of quarts to drive 1 mile. drove it in, getting it fix along with 90K service and replacing a bad key fob...
the price of driving a fun car.
