May need to replace your cylinder gasket: Engine overheating: This is the most common cause. Overheating can cause deformation of the cylinder head and cylinder block, exceeding the compensation capacity of the cylinder gasket and leading to their erosion and crushing. Cylinder head or cylinder block deformation/unevenness: Caused by manufacturing defects, overheating, improper installation (incorrect tightening sequence or torque of cylinder head bolts), or long-term high-load operation. Cylinder head bolt issues: Loose bolts, excessive stretching (fatigue), not tightened in the correct sequence and torque, unable to provide sufficient clamping force. .
