CDI270 oil leak (purchasing)

[RobC270CDI]

Please can anyone help.

I am purchasing a 2004 260CDI Avantgarde Auto (tip) and i have noticed what i expect to be an oil leak on a pipe (see attached Picture) it seems to be a small leak and the leaking down the pipe towards the silver thing (think this is a turbo). This area seems to be a little oil dampness.

Can anyone hazard a guess to what this is and how much this would cost to put right?

Any help would be welcomed

That's the breather pipe, a little wetness is normal but pull the cover off for a better look.

Thank you DiesalMan, what is the breather pipe and why is wetness normal. Thank you i will pull off the engine cover to see if the rocker cover gasket is ok too/filler cap etc. Do you know ant costings to fix any such faults ish?
