midway through putting my engine (SBC) back together and picked up the waterpump to have it cleaned and painted and came across this hole?!

hmmm...

is it a problem? I didnt have any leaks before it came apart but I have never seen such a hole before?

confused

sbc hole
 
I have. I don;t remember if sbc. Go to the parts store and compare to others, do you have a fan clutch Is it a big deal- try it or replace it now. I don't remember if you stated what the car is going to be used for. The only idea I can come up with is they didn't want fluid staying between the two bearings. One bearing goes out you get a warning before the fan goes through the radiator- just a thought' I still don't remember where I have seen it , but I have and used it. good luck mark

There is supposed to be a 1/8" vent hole there. Yours looks like either something rubbed it severly, or someone intentionally ground the nose of the water pump down. Personally, on a new engine, i'd replace it even if it weren't leaking. Its cheap insurance.

water pump # 2
 
After blow up- It looks a hammer and chisel hole. Casting looks bent also, the picture looses definition with much blow up. Not a drainor vent hole. Replace it if possible. mark
