So 2009 997.1 turbo, oil change at local Porsche mechanic, they claim overfilled by 1/2 quart, lots of smoke from exhaust when they turned it on, they emptied some and went by the electronic gauge until level ok. ran for a long time, but smoke doesn't want to stop. Smoke coming mainly from passengers side exhaust pipe. They disconnected the pipe coming out of the turbos and going into the intercoolers. The one on the driver's side was dripping some oil, not the one on the passengers side. They left pipes disconnected overnight to drain anything. They will clean intercoolers tomorrow and see if that gets rid of the dense smoke. I don't understand how oil got into the intercoolers. Did it flood the cylinders? No engine lights. Any recommendations for what they need to do? Engine been great with 50k miles.
