Engine leaks, anything to be worried about? Pics inside.

[jotto]

I know we all like pictures so after being told I could find the make of fuel system on the car simply by looking at it ( duh on my part ) I decided to have a look and take some pics.

Anyway, this is a 105k 2.0HDi engine and Im pretty pleased with how it looks.
I see the glow plugs are fairly well obstructed but at least they are on the front of the block!

I have 3 areas that I would appreciate advice on.
First is this one, rear right of the engine. As you can see the pipe is looking a bit wet from oil. Is this a case of strip and clean or should I be looking a bit deeper?


Next is below the power steering resevoir, looks a bit moist but am unsure if it is a leak or from when fluid was added. I would guess at a leak?


Finally, hopefully just a gasket, top left of engine. ( Behind 1st injector, top right of pic, sorry thought I had taken better pic of this one! )
