Leakage is mainly caused by loose seal on the lower face of the valve or cylinder head. Therefore, if there is carbon deposition on the valve seat sealing surface, it should be promptly removed. If the sealing surface is too wide or there are grooves, pits, dents, etc., the new valve seat should be repaired or replaced depending on the degree. Cylinder head warpage and cylinder head gasket damage also lead to air leakage. In order to avoid cylinder head warping and cylinder head damage, the cylinder head nut must be tightened in the specified order. Tightening torque should meet the requirements.
Leakage is mainly caused by cracks in the cylinder head or loose seals in the water. In order to prevent cracks from appearing, after the engine is started, it must be gradually warmed up and gradually increase the load; the engine cannot be overloaded for a long time; in a cold area, the cooling water must be exhausted after parking.
