A small amount of coolant leaking from the weep hole is normal. Small drips are OK. Longer streams or continuous leaking may indicate a problem. OE manufacturers developed the weep chamber as a way to hide the small drips so pumps are not prematurely determined to be failing. Those drips will remain in the chamber and evaporate as the engine heats up.
