Sure it can be repaired but doing cast iron repair on parts that have cycles of extreme heating and cooling is a bit of a specialty and can be very expensive. Often its only done when there is no alternative.

That said, looking at your crack I'd be tempted to drill a small hole at the end to stop it from growing and use something like furnace cement to stop the leak. Other than some labor possibly lost there isn't much downside to giving it a try.

PS - your question "can it be repaired" reminds me of a real old time welding shop around here back when I was in high school. It was a big old dirt-floored rambling barn and the big banner sign over the door gave the owner's name of course, and his slogan "We weld anything but aluminum heads and broken hearts".
