Oil leak, Skoda Octavia 1.8 118kW, 2011, manual

[Markoda]

Hello. I Just found an oil leak on the air pipe (with the yellow arrow and the 2nd pic). Where can the oil get there? The oil leak is also on the valve cover seal area (3rd pic).  Any ideas why is it leaking?

Pretty common. Looks like the engine bay could do with a good clean and maybe separate the intake pipe and clean. Then see how long the problem takes to re-occur.

 

The thing that improved it dramatically for me in the end was a new fine oil separator. (as pictured in your close up 3rd pic).

 

See thread.

The upper engine valve cover is also a common leak point but it doesn't look too bad to me.  Clean and monitor. It is a pretty big job to change the seal unless it is causing real problems.

@Markoda Did you get around to what caused the leak on the air intake pipe?

Mine look exactly the same, haven't gotten round to taking it apart though.
