What we have done on the engine of this type of car is a device that has been designed and built to prevent this event or major damage by scraping the valve seat on the piston. If for any reason the timing belt breaks or there is a disturbance in the timing of the engine and the car engine is out of sync or timing mode, the valve will prevent the valve from hitting the piston head. This in turn helps control and prevents engine failure, waste of time, and the huge cost incurred by the vehicle owner. Comparison of the piston produced shows that it is of the reduced price compared with what is present in the market and with a shorter time of production.
