[Fot] Crack in block fixable?

[fubog1]

I would consider repairing that with a "time-sert" solid wall insert, vs heli-coil.
That would restore the thread but the flange on top of the insert sits slightly below the deck. If the crack is open it will likely still allow a little water to get around the stud, right at the top of the hole.
I don't know if there's enough meat there but a couple vertical 1/8 pins down into the crack, one on either side of the hole, would fix that issue, or some careful peining and a bottle of Bars leak...

I was changing the head on my race 1296 engine and I noticed this crack (pictures attached) between a stud hole and the water jacket between cylinders # 2-3. I ran the engine hard last weekend at Thompson without any issues, I was changing the head because the "new" one is ported better and has larger valves.


Can this be fixed? I appears to only go down to the start of the threads but without some dye in it, I can't be sure.


Hoping to be at the Glen next weekend for the July Sprints but the spare engine isn't ready. Any suggestions?
