Engine cylinder block and cylinder head rupture, occurred in the vicinity of the valve seat or waterways and other thin-walled office. As we all know, the cylinder or cylinder head has a serious rupture, will lead to oil leakage, leakage and leakage, a direct impact on the normal operation of the engine, but generally easier to be found. The small cylinder or cylinder head cracks, it is not easy to observe, but it will leave the engine hidden trouble, thus causing harm and impact on the engine.
