His K&N appears from his post to be dry. All your reported symptoms indicate leaking oil. Once your mechanic (hopefully it's someone you have a good relationship with) gives you the report you can take care of it.

If you haven't, I suggest a good dealership or, preferable to me, a good independent Porsche mechanic to keep your maintenance up to date (especially the majors) so when you have an issue you have someone you can trust to steer you right. Good luck.
