Is that the highest point or is it coming from the seperator?

Separator????
How about valve cover breather.

WASH it all down so you can isolate what is leaking as there are several connections.

I've seen that same build up from spilling fuel during fueling.

Many models come with an oil seperator which is attached to the valve cover breather. I guess that model does not, since it goes straight to the turbo inlet. I am thinking this engine may have increased blow by. Pull the dipstick or oil cap, and see if you have lots of positive pressure. The rubber diaphragm in the breather may be blown out of place.
