TOYOTA Rush 1.5 16V Vios EX Valve - High Performance Upgrade

The valve guide plays a guiding role, ensuring that the valve can move in the correct straight line. At the same time, in order to prevent the oil from seeping into the cylinder, the valve guide is also equipped with a valve oil seal. The valve seat ring is embedded in the cylinder head. When the valve is closed, it fits tightly with the valve cone to form a perfect seal to ensure that there will be no leakage.
