Can the Engine Still Run After Major Overhaul Due to Water Ingress and Cylinder Block Cracking?

Engine after major overhaul due to water ingress and cylinder block cracking can still run, but it is best not to use the repaired engine as it poses significant safety hazards. Engine: It is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Impact of Engine Repair: Repairing an engine after water ingress is equivalent to a major overhaul, which will affect the engine's performance to some extent, but the extent of impact varies depending on the degree of water ingress. The repair process inevitably involves engine disassembly, followed by inventorying and replacing damaged components. Generally, original or aftermarket parts will be replaced at a 4S store.
As someone who frequently works on car repairs, I know that after an engine gets flooded and the cylinder block cracks, a major overhaul can usually get it running again, but it depends on the quality of the repair. If it's just a small crack, welding or replacing the damaged parts can restore the engine to near-normal operation. However, if the damage is severe and causes significant deformation, the engine may lose some power and run noisier after repair. I've seen many cars run tens of thousands of kilometers without issues after such repairs, but they require a break-in period of a few hundred kilometers—like driving at low speeds to let the parts settle in, while frequently checking oil pressure and coolant temperature. The main problem is that post-overhaul reliability decreases, making oil leaks or burning oil more likely. I recommend regular oil changes and avoiding aggressive driving. Additionally, such repairs can affect the vehicle's resale value, so it's best to disclose the repair history when selling to ensure a fair deal.
