Hello, I have seen this minor oil leak on the left engine side that facing the firewall for sometimes, but just found time to bring to dealer. After some searching on Internet, I suggested to them that it might be leaking from the timing chain cover. After some inspection, they called me and confirmed that it's from the timing chain cover, and ordered part to replace it. I will get the car back sometime today, will post if anything new. Just a head up so you guys can check it. You have to look with the flashlight on the left side of engine facing the firewall.
