Default Re: Is my block dead?

That's where they crack from freezing water. I had one just like it and was able to nurse it along with Marine Tex epoxy for over 20 yrs. You really need a mechanical seal. There is no pressure, but when the epoxy falls out due to corrosion, it will leave you stranded. You never know when it will let go. Epoxy can last 10 yrs or 1yr. Braze, weld, solder however you can get it sealed and keep antifreeze in it year around.
