Leaking water pump 51 Super Six

A buddy has a 51 SS with a 262 which is his daily driver, and the water pump started to leak from the weep hole. He got a rebuilt replacement from one of the Hudson Club vendors and it also leaked immediately. He has gotten 2 more replacements in as many weeks, and they all leak. I am thinking there is another issue......any ideas? Blocked passages? I find it hard to believe he got 3 bummer water pumps in a row. Everything is stock on the motor and he is using a 7psi cap.
The car has about 40k original miles.

Thanks
Don

  • The only way it can leak form the bleed hole is if the seal is no good.  Sounds like against all odds, he has received three crook pumps. 
  •  A Hudson buddy of mine had a very similar situation, 3 water pumps in a row leaking from the weep hole, with a 7lb cap.  He finally figured out that his over flow hose to the coolant recovery tank was crimped completely.  He fixed that and no more problems!
  • What a great tip Dover! Thanks for sharing.
  • When the weather isn't warm enough to require pressure in the system, I leave my cap on loose.
