There is a slow leak in the front of my car somewhere. My garage floor has an oil spot just under where the front of the engine is positioned, pulley area. It looks like transmission oil, but that is way too far back to be leaking there. The oil is clean and brown, so its not motor oil because that is black. Even if my motor oil was fresh it should be purple since ive been using royal purple. Oil pan was new from the swap and is dry around the edges. Can't be brake or clutch lines, not only are those not positioned there, but i'm using super blue fluid. Can't be power steering because that is red.
Could it be the A/C compressor? Is R-134A or whatever the new freon is called an oily substance?
I'm stumpped here

, anyone know what it might be?
