What is leaking oil? (Pictures inside)

[Walorus]

I took some pictures from the top of the engine and I'm wondering what it could possibly be. It's a 986 porsche boxster.

Here is an overall view, the red is where it looks wet and the purple is where it's dry. http://i.imgur.com/Q86Vlwp.jpg

It seems to be mostly wet on the driver side, but there is a small part on the passenger side which is a tiny bit wet. The far passenger side is dry though.

[This is the passenger side of the engine](http://i.imgur.com/FcshPJX.jpg) It's hard to tell but it is dry.

[This is the driver side of the engine](http://i.imgur.com/wudSFsd.jpg) which you can compare and see it's quite wet. [Another view of the driver side](http://i.imgur.com/1Mz4wDa.jpg)

And this is the tubing that looks like it connects to the power steering where a [part of it looks a bit wet](http://i.imgur.com/uHvKGPX.jpg) compared to the rest of the tube

Any idea as to what could be the problem?
