The crack is between the forward exhaust port and the water pump mount on the passenger side of a 37 block on the outside of the block.
The opposite bank seems tight, it has been holding 25 lbs for a day and a half. this side leaks down to zero in a half hour. I haven't found any other leaks, but without it holding over time I can't be sure it's crack free.
How would YOU fix this? would Lock N Stitch pins be the best?
I couldn't take a decent photo of it bubbling with one hand while spraying with the other hand, so here's a video. Anyone else see a crack like this? Seems like an odd place to crack without other damage, so I'm concerned I'm missing something.
