Do you know any machinists or foundry worker or engineer ?

I'll investigate that route. Now that I've seen the wheel, the extent of the problem is more concerning. There were over a dozen pinhole leaks clustered around different spots on the wheel. 3 areas on the back side, 1 on the face. I'm not sure about a sealant being adequate due to the dispersed nature of the problem. It might be worth a shot.
At least, now it does not appear to be an actual crack, which on one hand is good. But on the other it is clearly oxidized pretty thin in a few spots, so it may not be long for the world anyway.
