Cracked Block

Here's what will have to be done to fix it. Each end of the crack will have to be found. Not "maybe" found, but FOUND.

Then, a hole will have to be drilled at each end of the crack. This stops the crack from continuing.

Next, it will have to be welded by some who KNOWS how to weld cast iron. All that said, YES, it can be fixed. It will not be cheap.
