Anyone have any issues with milodon water pumps?

I put a new milodon high flow water pump with milodon t-stat in about 2-3 years ago and i just noticed a few drops of coolant hanging at the weep hole opening after car has been sitting for about 3 weeks while i was working on the brakes. i started and ran it for about 10-15 minutes and No leaks with it running. Its sat about 5 hours before i checked it again and there is one little drop of coolant at the weep hole. Wtf the murray water pump lasted about 6 years before i replaced it due to shaft play
