Does anyone know what a bad one sounds like?

I have this clicking, and I am trying to pinpoint what it is without takin the cams and everything out...

Does a LMA click (most of the time) consistantly, and sometimes randomly?

The noise is cooming from the drivers side of the #1 cylender near where the intake manifold meets the head. That is where the LMA's are right?

Also, how can I tell if it is bad by looking at it?
