Dreaded oil leak on the wifes car, took it apart and there was oil the wrong side of the turbo feed pipe on the oil cooler so swapped them for new ones.

Car back together, removed the under tray, cleaned up all the oil i could and started the engine. Noticed a small week coming from above the starter motor. I cant see the source but it's running around the starter motor and then dripping down from there. Couple of pictures attached.

Whats weird is it's 'clean' oil. Not the same black stuff that I cleared up off the drive and from the under tray. It's not quiet red of transmission fluid plus with it leaking from above the starter motor I don't think this could be ATF?

What are peoples thoughts?
