Yes. You have developed a leak.

Odds are you also got a new radiator cap at the same time, so your pressures have increased a tick. Is it on the t-stat housing or the water pump housing? If T-Stat, it's the O-Rings in the down pipe. If the water pump, IDK because the weep hole is on the bottom unless the pulley is slinging it up and over.
