<font size="2" color="black" face="Arial, Helvetica, sans-serif">I<font size="2"> would consider repairing that with a "time-sert" solid wall insert, vs heli-coil.<br>
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.<br>
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...<br>

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