Hydraulic Tappet & Inlet Cam Lever Assembly
Sold each – 8 required per car
The hydraulic tappet and cam lever assembly for the inlet
valve is a precision-engineered valvetrain component used in Porsche Macan
2.0-litre engines. Working together, the hydraulic tappet and cam lever convert
camshaft motion into controlled inlet valve operation while automatically
maintaining correct valve clearance using engine oil pressure.

Diagram ref no 7
This assembly plays a vital role in ensuring smooth engine performance, quiet operation and efficient air intake—particularly important in turbocharged Porsche petrol engines.
What Does the Hydraulic Tappet & Inlet Cam Lever Assembly Do?
The camshaft acts on the cam lever, which in turn presses
against the hydraulic tappet to open the inlet valve at precisely the correct
time. The hydraulic tappet uses oil pressure to compensate for thermal
expansion and wear, ensuring:
- Accurate inlet valve timing and lift
- Smooth idle and throttle response
- Reduced valvetrain noise
- Consistent air intake for efficient combustion
This system allows the engine to operate efficiently across all load and speed conditions without the need for manual valve adjustment.
Why Do Hydraulic Tappet & Cam Lever Assemblies Fail?
These components operate under constant mechanical load,
high temperatures and reliance on clean engine oil. Common causes of
failure include:
- Oil contamination or sludge build-up
- Extended oil change intervals
- Wear to cam lever contact surfaces
- Internal tappet pressure loss
- Insufficient lubrication at cold start
Symptoms of wear or failure may include:
- Ticking or tapping noises from the cylinder head
- Rough idle or hesitation
- Reduced engine efficiency
- Accelerated camshaft or valve wear
Why Replace the Inlet Tappet & Cam Lever Assembly?
Replacing worn components helps restore:
- Quiet, refined engine operation
- Correct inlet valve timing Improved drivability and throttle response
- Protection against further valvetrain damage
Ignoring tappet or cam lever wear can lead to costly damage to the camshaft, valves or cylinder head, particularly on high-revving turbocharged engines.

Diesel Engine Hydraulic Tappet / Valve Lifter
This engine hydraulic tappet (also known as a hydraulic valve
lifter) is a precision component used in Porsche diesel engines to
maintain correct valve clearance automatically. By using engine oil pressure,
the tappet ensures smooth valve operation, quiet running and consistent
performance across all driving conditions.
Fits:
Diagram ref no 11
In modern Porsche diesel engines, hydraulic tappets play a crucial role in durability, refinement and emissions control—making them an essential service and repair component.
What Does an Engine Hydraulic Tappet Do?
Hydraulic tappets sit between the camshaft and valves, using oil
pressure to compensate for thermal expansion and component wear. This allows
the valve train to operate with:
- Correct valve timing and lift
- Reduced mechanical noise
- Improved combustion efficiency
- Lower internal engine wear
By automatically adjusting clearance, hydraulic tappets eliminate the need for manual valve adjustment and help maintain optimal engine performance throughout the rev range.
Why Do Hydraulic Tappets Fail on Porsche Diesel Engines?
Over time, hydraulic tappets are subject to heat, oil contamination
and mechanical stress, particularly in high-torque diesel engines.
Common
causes of failure include:
- Oil sludge or poor lubrication
- Wear to internal check valves
- Loss of hydraulic pressure retention
- Extended oil change intervals
- Contaminated or incorrect oil grades
Symptoms of worn or failing tappets may include:
Ticking or tapping noises from the cylinder head Rough idle or misfiring Reduced engine efficiency Increased valve train wearWhy Replace Worn Hydraulic Tappets?
Replacing worn hydraulic tappets restores:
- Quiet and smooth engine operation
- Correct valve timing and combustion
- Reduced wear on camshafts and valves
- Long-term engine reliability
Ignoring tappet wear can lead to accelerated damage to the camshaft and valve train, resulting in significantly higher repair costs.
