solenoid manifold 5 assembly is leaking at the bottom valve. Is there an O ring inside the black box behind the C clip and red button?

Where the red button is located is there electromagnetic solenoid. These are easily removed. Once off you will see an o-ring that seals the solenoid to the manifold. I doubt the leak is at this ring. It's more likely the solenoid itself. First, make sure it's working. Depending on whether it is a normally open or closed valve will determine how it should operate. It's probably normally closed. If so, no air should leak when there's no voltage applied. With voltage applied the valve should change state.

The solenoids, without the electromagnetic coil are about $45. The entire 5 port system is less $400 (both prices are from memory). So, you might want to invest in the entire block and use the old one for spare parts.

Thanks for your response. It leaks with key on or off. Also it leaks regardless where the leveling valve is set.
