Is it true that the Bestune X40 needs to have its cylinder head replaced every 20,000 to 30,000 kilometers?

It is true that the Bestune X40 needs to have its cylinder head replaced every 20,000 to 30,000 kilometers. Conditions for cylinder head replacement: If the cylinder head has already deformed or the cumulative wear from grinding exceeds 0.50MM, it is recommended to replace it with a new one. Cylinder head: The cylinder head is installed on top of the cylinder block, sealing the cylinder from the upper part and forming the combustion chamber. It is frequently exposed to high-temperature and high-pressure gases, thus enduring significant thermal and mechanical stress. Causes of engine cylinder head deformation: The cylinder head is made of aluminum alloy material and will not deform under normal use. If deformation occurs, it is usually due to a lack of coolant. This is because the combustion chamber of the cylinder head reaches temperatures of several thousand degrees during engine operation, and under normal conditions, the heat is dissipated by the circulating coolant. Without the coolant, the cylinder head continues to operate at high temperatures, leading to deformation.
