"Replace piston ring in the cylinder liner does not need to wear down. If the cylinder liners are worn. Need Cylinder Boring. And replace the oversized piston rings. Please check the roundness of cylinder liners. And boring lines.*This video shoot. Engine overheated cylinder head gasket damaged Replace cylinder head gasket set and piston ring group. And cylinder liners is not damaged. Replace the piston ring STD. To improve the situation on the engine oil."
