You might check that the bolt isn't bottoming out. The bolts
from the factory are not standard length, they are special.
Often they are misplaced and a hardware store replacement bolt
is used in its place. With the lock washer crushed it appears
that it's tight but in reality it is bottomed out just a
fraction of a turn before it is actually tight against the pump
body. This gives the impression that the gasket is bad and not
making a seal or suggests there is a minute crack in the pump or
block. You should not need a cork or thick paper gasket for the
water pump a stock 1/32" gasket with Permatex #2 is perfectly adequate.
