Hydraulic Tappet / Valve Lifter
Sold each
The hydraulic tappet / valve lifter is a precision
valvetrain component used in Porsche Macan 2.0ltr, Cayenne S Hybrid and
Panamera S Hybrid engines to automatically maintain correct valve clearance. By
using engine oil pressure, the tappet ensures smooth valve actuation, quiet
engine operation and consistent performance under all driving conditions.
Fits:
Diagram ref no 6
In advanced Porsche petrol and hybrid powertrains, accurate valve control is essential for efficiency, refinement and long-term engine durability—making hydraulic tappets a critical service component.
What Does a Hydraulic Tappet / Valve Lifter Do?
Hydraulic tappets sit between the camshaft and the valves,
using pressurised engine oil to compensate for thermal expansion and component
wear. This allows the valvetrain to operate with:
- Correct valve timing and lift
- Reduced mechanical noise
- Smooth idle and throttle response
- Improved combustion efficiency
By eliminating the need for manual valve clearance adjustment, hydraulic tappets help maintain optimal engine performance throughout the engine’s service life.
Why Do Hydraulic Tappets Fail?
Hydraulic tappets operate in high-temperature, high-load
environments and rely heavily on clean, correctly pressurised oil. Common
causes of failure include:
- Oil contamination or sludge build-up
- Extended oil change intervals
- Internal wear of the tappet mechanism
- Loss of oil pressure retention
- Incorrect oil specification
Typical symptoms of failing tappets include:
- Ticking or tapping noises from the cylinder head
- Rough idle or hesitation
- Reduced engine efficiency
- Accelerated wear to camshafts and valves
Why Replace Worn Valve Lifters?
Replacing worn hydraulic tappets helps restore:
- Quiet, refined engine operation
- Accurate valve timing Improved drivability and efficiency
- Protection against further valvetrain damage
Ignoring tappet wear can result in costly repairs to camshafts, valves and cylinder heads—especially in hybrid engines where smooth operation is critical.
