Thought about that. I can't even SEE the crack, it's so small. It's right at the bottom of the drain hole bung. At the weld. Drained it yesterday, and no drips today. I put some cotton rope inside and pulled it back to the bung with a bent coat hanger. Plan on it soaking all night and tomorrow, Brake clean and JB. I think I'm gonna really push the JB in and then give it a good coat.
