Do not use the handbrake in the parking lot and leave the car with a manual transmission in gear in the old fashioned way?
Experts say that this is a dangerous habit that can lead to serious damage.

The gas distribution mechanism of modern engines is no longer designed to withstand a high load when the ignition is off. When parked, the pressure on the belt increases, the teeth move, as a result, the operation of the mechanism is lost. As a result, there is a risk of damage to the timing settings, which leads to engine failure. When starting, the pistons hit the valves and damage them.

Therefore, when parking, you must always use the hand brake and tighten it harder.
