"Blow By" Oil Residue on Power Steering Reservoir

I seem to be getting some oil residue being blown onto the power steering reservoir tank on the driver side near intake cones. Trying to figure out where this is coming from. Any ideas? Could it be diverter valves blowing out oil to atmosphere carried over from PCV loop? I'll add a picture.
