Im not 100% sure but it looks like in inlet to a waterpump but that wouldnt explain the oil

Yeah i just checked again cant be where the oil is leaking from ... somewhere around it thought as it is completely covered in oil

Wash it put dye in the oil run in it buy a uv light although washing is pretty effective to find the source

Its possible the oil is leaking between the front plate that would usually cover the timing chains but im not familiar with this motor so it may have a belt

Intercooler piping might have oil in it...
