Common signs and symptoms of a broken crank in a car engine include loud knocking or banging noises coming from the engine, engine misfiring or stalling, loss of power or acceleration, and visible damage or oil leaks around the crankshaft area. If you notice any of these signs, it is important to have your car inspected by a mechanic as soon as possible to prevent further damage.
