I have a small leak coming from the rear center of the engine that drips down on the passenger side USA and is coming off the transmission. I have dye in the coolant and an awesome blue light, but I can't see the origin. Anyone have any idea what might be leaking here? Thanks for your help!

I found a leak in mine but it was closer to the passenger side it was the small “hose” between the oil cooler and engine block. There are tubes that run under the intake as well.

This plastic Union adapter breaks down and leaks right on top of the transmission. This is an 09 , maybe the 07 is set up different.
