Hi all encountered my first issue. Found oily soot whilst cleaning the engine bay. Would anyone like to advise on what the issue could be. No oil residue on the driveway that I can see. Any way I cleaned the area and ran the car at idle 5 mins to observe. No visiable signs of any leak around that area. Few weeks ago I did see wet ATF pipe seemed like it was oil, may be it was same issue finding it's way down the pipe. I cleaned that area up nothing since Any help be appreciated. Thanks
