1.2 BZG engine oil leak

Hi

Got a 2008 1.2 liter 3 cyliner BZG engine. Only 110000 km. Its leaking oil. The issue is that the engine is totally dry. Front, left, right and back. Can not find one drip of oil. However the linkarm (right ride of car) and about 1 meter rear is totally soaked and i notice about 1-2 dl oil gone on 100-200 km driving. It only comes out after driving so stop dripping once stop.

I cant see any house, pipe etc above the linkarm. Again nothing on the backside of the engine. Tray, belt side etc. Attaching two photoes. one from below the link arm and you can see its wet and oil have sprayed rear on the chassie. ALso a bad photo on the back of the engine. No oil what so ever.

Any ideas? Thanks guys
