2016 B8.5 Coolant leak

[Haap]

Need help isolating this coolant leak!

2016 B8.5 S4 50k miles

Noticed a static leak overnight for about two days in a row, about 6-10 oz would leak after sitting overnight. Pressure tested and was unable to see exactly where it was coming from, but it was leaking at a steady rate, pooling up right above oil pan and dripping down the front of the block. Deductive reasoning led me to the water pump, but after pulling the pump, I am not 100% sure it was coming from the seal, could it have been coming from the weep hole?

I planned on replacing pump, thermostat, and the front radiator crossover coolant pipe, at the same time. After pulling the blower, I noticed some pooling of oil under the PCV, so I picked up a PCV valve.

Any assistance would be great appreciated, pictures of front block with Waterpump, PCV, and thermostat removed.

I just replaced my water pump on my low mileage 2015 S4...apparently the gaskets on our water pumps are garbage...that would be my bet.

I replaced mine and could see the coolant stains immediately below where the gasket failed to confirm....no guess work involved.
