One done with Marine Tex as Jerry suggested. Shows crack that was fixed 20 years ago and no issues even though it runs through freeze plug holes. Sand blasted, roughed up with 24 grit disc and crack "V" grooved about 1/16 deep. Use Marine Tex as it was designed for liquid rather than other epoxies like JB Weld. Sorry no finished pics. Used rubber expandable freeze plugs.
