I have a small coolant leak, and can't seem to pinpoint where it is coming from. I did some work on the car where I had to take the throttle body, egr valve, intake duct, and supercharger off, and replace all the small cooling hoses that goes through the throttle body, egr valve, and replace both heater hoses under the supercharger while it was out. I don't think it to be coming from a hose that isnt securely on, since I felt around most hoses and didnt see coolant around the hose connections. There seems to be coolant on along the left side in the valley of the block near the knock sensor, and I felt coolant under the intake duct, and under the black piece on the throttle body where the throttle cable connects, and there is coolant where the throttle body connects to the intake duct (see picture). Any idea where to look?

Here are some pictures:
