Oil leak, by radiator area, Not Sure where coming from? HELP

[ZoomZoom88]

Hello Everyone, 🙀

I got done yesterday doing my 2nd power steering flush for my 2000 LX470 and when I woke up this morning, I saw oil under the car in front of the radiator area. I checked underneath and no leaks from the drain plug, oil filter or engine area. Seem there is oil on bottom side of the radiator in the back/front of it. I am guessing there is an oil coolant line(s) leaking, has anyone dealt with this before? Easy for me to repair?

It could be a leak from the power steering cooler which may be built into the radiator (as are some auto trans coolers) or a PAS fluid pipe/hose around the engine bay

Is it coming from the driver's side, right under or near the oil filter?  If so do a search on "Toyota 2UZ-FE Engine Oil Leak" for a great video on where this leak originates.  I just replaced both of these seals myself and it's a PIA but definitely doable with the right tools.  I literally threw out the clothes I was wearing though.  It was that messy.
