Dale leaned against the bench. The decision facing him was not simply whether he believed his son was clever; he had always known that. It was whether a boy with months of concentrated practice, guided by an old mechanic's lifetime of knowledge, had a reasonable chance of repairing the machine that kept the farm working. He also had to weigh that chance against the cost of doing nothing while replacement parts remained uncertain.
Silas did not rescue Jonah by insisting that his grandson was ready. He reminded Dale of the practice failures, the tested successes, and the limits they had learned to recognize. Then he said something that made the room quiet. "I wouldn't put a man's field on the line for a boy's pride. Not even my own grandson's. But I'd be lying if I said he hasn't learned what most fellows never take the time to study."
Dale looked at the engine and the financing folder sitting on a nearby shelf. He asked how long a careful assessment would take, and Jonah said he needed to clean the casting fully, map the damage, and review the critical areas with Silas before promising anything. That sounded less like a desperate gamble than Dale had expected. He nodded and said they could take the time for the assessment, but the decision to proceed would still depend on what they found.
For the next day Jonah barely thought about anything else. At school he stared at the clock and tried to concentrate on algebra while his mind returned again and again to the branching line in the block. On the bus ride home he saw farmers preparing planters and spreading fertilizer across fields that were almost ready to work. Every machine in motion reminded him of the one sitting silent in his grandfather's shop.
When he arrived, Silas had already laid out the service drawings and the inspection notes from the previous evening. They spent hours cleaning the casting and examining the complete fracture pattern, looking especially closely at the areas where the crack approached features that carried significant load. A repair that made the cooling jacket watertight but weakened the block mechanically would not be an acceptable success. Jonah measured, recorded, and asked questions until Silas was satisfied that the boy was no longer trying to see what he hoped to see.
The final assessment was cautious but not hopeless. The most heavily loaded internal structures showed no evidence of the fracture spreading into them, and there appeared to be enough sound metal around the damaged water-jacket section to make a mechanical repair
