Always loved the R36 passat and now looking to be a owner of the passat 206tsi

Hey guys
I'm slowly pulling the good bits off my written off 2011 Fabia 77TSI.
Today I removed the inlet manifold/plenum chamber and found a pool, maybe half a cup, of treacle like engine oil, in the lower part of the plenum chamber
There is a passage right next to the number...
