Clattering hydraulic tappets: causes, consequences and a solution

Hydraulic tappets are important components in the engine that ensure that the valve clearance is automatically compensated. But what happens if these important parts are defective and what causes hydraulic tappets to clattering anyway?

Clattering hydraulic tappets can have various causes:

• Wear: over time, hydraulic tappets wear out, especially with high vehicle mileage.
• Lack of oil: low oil level or low grade oil can affect the lubrication of the hydraulic tappets.
• Dirt and deposits: contamination in the engine oil can clog the fine channels of the hydraulic tappets.
• Air in the hydraulic system: air bubbles in the oil circuit can impair the function of the hydraulic tappets and lead to clattering.

Defective hydraulic tappets are usually noticeable by a characteristic clattering or ticking noise in the engine. This noise can be heard particularly clearly when starting the cold engine and may increase over a longer period of driving. Another sign: the engine runs more unevenly and loses power.

Ignoring the signs of defective hydraulic tappets can result in consequential damage. Possible consequences include:

• Increased wear of other engine components: insufficiently lubricated parts wear out more quickly.
• Engine damage: in the long term, serious damage to the engine can occur, resulting in expensive repairs.
