There are multiple sources of oil leaks on a Boxster and oil has an uncanny ability to leak in one place, run down, and then drip from somewhere else entirely.

The best way to find where the oil is coming from is to clean it up and then inspect it daily until you find the exact source.

It is possible that oil is leaking from the cam covers but don't assume that this is true unless you know for sure. Two mechanics told me that the cam covers on my Boxster were leaking and it would cost $1400 to repair. After cleaning up the engine and inspecting it carefully, I found that the leak was actually caused by the spark plug tubes - which I replaced myself for about $60.
