Default Water leak from new block

Hey guys. I just finished putting my 92 VR4 back together after getting a new block--which was from a 93-99. The car fires and runs but there is a major water leak coming from the front driver's side of the engine.

The water is dripping down from the oil filter so it must be coming from above that. I initially thought it was the freeze plugs under the ac compressor bracket but I stripped all that off and those are fine.

Any idea where it might be coming from. Almost looks like it might be under the timing cover, but I really don't want to pull it off with the engine still in the car.

Possibilities will surround the water pump. If it is not the gasket or o-ring, then worse case scenario is weep hole i.e. seized. Worst case scenario albeit less likely is HG. You will need to remove the covers; recommend pressurizing the system before running it further.

Do a pressure test with the timing cover off.

Thanks! Got the timing cover off. The leak is definitely coming from the weep hole. The pump makes a scratching noise when being turned, too.

Not sure what caused it to fail like that; I thought it was a new pump. Anyhow, another one is on the way.
