Coolant leak, drivers side lower timing cover?

For sealing those bolt threads into coolant passages, I prefer Permatex #2(?). It comes in a small (white)plastic bottle with a brush applicator top. It's a thickish dark brown liquid, that is alcohol soluble. It never hardens, and can be reusable in a pinch. I'm not 100% positive, but I think that is what MA Mopar used back in the day.
