Solution to my leaking water pump weep hole?
I second the suggestion to insure the leak is from the weep hole. My 1969 slant was leaking from the short top hose of the water pump which runs from the bottom of the head. It is very hard to work a regular rubber hose in there, so use 5/8" silicone hose which is more flexible and lasts much longer. If not a 225, there is even less room so might need to removed the water pump.
Similarly, in my 2002 Chrysler 3.8L (Post 51), what I thought was a water pump leak turned out to be from a cracked rubber cap over a stub on the rear of the water pump housing (blocked off when an oil cooler like mine). I replaced with silicone hose with copper plug.
