what do you make of this
 

I pulled my motor and found this "stain" where the intake would be. It looks like coolent was leaking to me but from where?

Most likely that vertical coolant line on the rear side housing.

I would say that as well, or you could have had a water sensor leak from the rear of the thermolstat housing.

There's also a coolant line going into the back of the thermostat housing from the rat's nest - could have been from there. Regardless, nasty coolant sat puddled there for a while to make that stain. Clean green coolant wouldn't do that.

Thanks guys I was hoping the engine wasnt leaking, and the coolent is new.
