coolant leak

so this could possibly be a head gasket. only thing keeping me from confirming that, is that the oil looks perfect.
I also think it might be the water pump housing, somewhere along the seals. if that's the case, I plan on buying a supercharger oil kit with both water pump seals. the only reason I have to think it is not the water pump, is because it looks like there is a stream coming from the head. And it appears to be higher than the water pump.
I'll post detailed photos.
If you have any suggestions or feedback, it would be greatly appreciated. If you want to tell me to search the forum, i have already done so. Thanks

I cannot see too much in that last picture but have you checked the o-ring fitting where the water pump connects to the engine? There are two "gaskets" there, one where the part connects to the engine and the other where the water pump slips into this separate part.

Let me see if I can find a picture.

You have to remove the two bolts holding this part before you can remove the water pump itself. Removing the driver side supercharger horn and the BPV also makes the water pump replacement easier, do not have to remove the supercharger.

With everything you seem to have going on there, seems like the front crank sensor o-ring is shot, all that oil the coolant seems to be on top of. I don't know how long you plan on keeping your car,if it were me, since I'm taking all those parts off anyway, I would just remove the Supercharger and change the oil. Once that is removed you have better access to all the seals you are changing, plus you would be able to service the supercharger and take care of the water pump. just a thought..

Between the coolant and the oil grunge does appear that you have the crank sensor o-ring and water pump to replace. I would also consider replacing the t-stat along with the orange and green gaskets that go on the supercharger duct (black plastic) from the throttle body to the supercharger.

Ignore the shipping as the site will try to charge you per item for shipping, but I'll just put it in one box and only charge you for one box.
