How about some photos where you are not zoomed in do tight? Unless one is whiz on components and their locations on the engine, the above photo leaves most scratching their heads.

 

 

I understand you trying to get a photo of the leak but what about an overall photo showing the area. Maybe someone pointing to the area you think is leaning. Photo about a foot or two away or both distances.

 

 

Here is the Ford Workshop DVD procedure.

 

To help with everyone's alignment, the photo posted above is sort of upside down. The top of the picture is the front of the engine and the bottom is the back. The black line on the right is the coolant hose from the top of the radiator and the gray line crossing over the upper left is the hot intake headed to the intercooler.

I'd be suspect of the sensor that's right there. Pull the connector and see if there's a/f in it.
