Underneath the manifold on the front side of the engine ( towards passenger) is where the coolant hides attach to the thermostat area
Thank you Abscate. I will definitely be looking around that area. Thanks for all your help.

Report on my attempt to repair the leak.
I took Intake Manifold out and found no obvious areas for the leak. Cleaned everywhere and tighten the thermostat screws, especially the lower one that is hidden. Assembled all back and the car has been driven for an hour or so. It started to leak again. Upon inspection with all assembled and been hot I was able to see that the upper area of the engine block is all dry and clean. The banjo bolt connecting to manifold is all dry and clean, and thermostat area is dry and clean. The leak is in the lower area either behind or right next to Oil Separator container. I didn't take Oil Separator Container out when I was there but I don't believe there are any Coolant lines going through either. Is it possible I have a crack in the Aluminum Allow lower engine block. If I do, is it even fixable without removing the engine and breaking the bank??? I thinking of taking to the mechanic to put some die into a coolant and see exactly where the leak is. Any advise will be greatly appreciated on this matter.

YEah, if its not in the PVC on the left side of the engine, (facing front of car) its a block leak. Could be a freeze plug or something fixable without engine removal though.
