If a hydraulic tappet generates noise during drives, the need for replacement should be considered. On some large vehicle models, the problem can be solved by adjusting the tappet. But such adjustment is not possible for typical family cars due to the hydraulic nature of the tappet on board, and replacement is the only solution. The clattering sound of a hydraulic tappet results from wear of components along their length and gap, and may grow more noticeable over time. In serious cases, the normal function of the engine valve may be impaired, which will in turn lead to improper gas mixture. If things go worse, the base will be worn, and the problem can then only be solved through repair or replacement of the cylinder cover.
The length of the hydraulic tappet is adjusted by the pressure of the engine lubricant, thus making compensation for and minimizing the valve clearance in the valve transmission system due to thermal expansion, wear, or other factors. The hydraulic tappet allows the engine air distribution mechanism to maintain good airtightness during work and ensures smooth operation of the engine.
