I take it that this oil is normal here?

Hi I have taken off the MAF Sensor to replace it and noticed this oil here, see photos. I take it that this is normal for this to be here, as it comes out of the breather pipe, but I just thought that I would check while I have the MAF off. MAF looks clean.

If that is air flow to turbo, then i suspect that before the connection of the breather pipe all is good, the oil comes from the breather pipe and goes back into engine via turbo. I think its just the accumulation of fumes. On my ML270 i fitted an oil catch can into the breather pipe, which did reduce the oil a bit, but did not stop it completely, but i achieved the end result of stopping an oil leak.
