Suggestions to find coolant leak

Hi all, trying to chase down a coolant leak. Steady drip at front passenger side corner of the lip of the oil pan (see arrow). I already replaced the lower hose (radiator to water pump) as it looked pretty worn, but that didn't fix the problem. Engine is dry on top where water hoses connect. Am I looking at waterpump, or timing cover next? Engine is a 340, the car is jacked up so that front wheels are off the floor. Appreciate any suggestions - thanks!
