Did I blow my AOS autocrossing? Help me diagnose it!

[DG Boxster]

The Boxster has been fine all day, with normal oil levels and no smoking at startup. I think the auto cross driving caused some oils to somehow get into the intake, but apparently this isn't abnormal for these cars after "spirited" driving.

Thanks to all who responded. I'm going to continue to watch carefully, and check the suction at the oil cap every once in a while as well.

I have found evidence that this car was well cared for, so it may not have the original AOS. I wonder if I can find a part number or date of manufacture on the outside of the AOS. If anyone knows where these markings are, feel free to post a picture.

Thanks again, this is a great forum.
