    hey! i have a 3406b water pump is leaking out weep hole on startup only when cold, seals after 30 seconds, summer weather it dont leak at all, iv left it alone because i replaced that pump 2.5 years ago with a pump directly from cat if i remember correctly paid round 1100 bucks canadien for it, and it started this deal bout a year or so in, anyway! does anyone know a good place to get a aftermarket pump so i can keep my core thdn install a seal kit in my old one paint it and shelf it til next time cause i think its gonna happen again in future, if so does anyone have any part numbers?for seal kit and pump ? or just say screw it get another cat one?

    Best to get a new one. It will leak more and more as time goes by.
