The leak is right on the engine. I can see it plane as day. Its a little half circle cap thing and it drips really slowly. How do I stop it?

I think I have a dead engine at work, so if I can locate the part I will get a better idea as to what is going on. I found the pic, it looks like the rubber 1/2 moon grommet under the rocker cover, this will not be the leak, check around the rocker cover and see if you can find any evidence of coolant leaking, I will still look at the engine at work as well.

See the pic, you will see the 1/2 moon seal on the rocker cover, is this the place you see the leak?

There is no coolant behind that seal, I would get the cooling system pressure tested and look around the thermostat housing and the thermo switches on the drivers side, I do feel that coolant is working its way around the rocker cover and coming visible at the front, get this done first.
