The valves move in pressed guide bushings. The valve seats are pressed into the cylinder head. Valves are driven by camshaft cams through cylindrical hydraulic tappets (hydraulic pushers), valve clearances are compensated automatically and there is no need to adjust them. Oil channels are made in the cylinder head to supply hydraulic pushers and other elements with oil.
Permissible Warpage (flatness) the mating surface of the block head and engine block is not more than - 0.05 mm. Nominal / minimum height of the engine cylinder head - 140.0 / 139.70 mm.
