What damage does stalling a manual transmission car cause?

[ColinMarie]

Stalling a manual transmission car does not cause damage, similar to how an engine start-stop system frequently turns off and restarts the engine. The only difference is that one is a normal shutdown, while the other is a forced stall. Here are some additional details: 1. A forced stall can have minor effects, such as subjecting the engine to some impact. The engine, which was rotating smoothly, suddenly experiences a significant force preventing it from turning, leading to an instant stall. This sudden force can cause some impact on the crankshaft. 2. After a forced stall, the cylinders may retain a significant amount of unburned gasoline, which can easily lead to carbon deposits. However, the impact is minimal, as restarting the engine promptly will burn off the excess fuel. Restarting might be slightly difficult due to the overly rich air-fuel mixture, but this can be resolved by gently pressing the accelerator while starting the engine.
