Coolant leak around engine studs?

Now that I think of it, easy way to do this would be to temporarily plumb the radiator to the WP housing, then cap or loop the remaining openings (heater ports, rear housing/TB lines, etc.), then rent/borrow a coolant system pressure tester from the local auto parts shop. Fill with water, pump it up & see if the pressure holds; if it doesn't hold you'll find out quickly where it's leaking from.

This makes sense. I'll look into it. Right now I just have about a gallon of coolant in the block itself. Previously this was enough to leak around the engine studs but no leaks after about 15 hours so far.

EDIT: Actually, I just went out and checked again and it looks like there's a small leak in one of the plugs in the water pump housing. Fortunately, that's an easy fix.
