Hydraulic Tappet and Cam Lever assembly for Inlet. Porsche 95B.1 / 95B.2 Macan 2.0ltr  ❭  95810941710

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.

Fits:

• Porsche 95B.1 Macan Petrol 2.0L 237Bhp 2014-18
• Porsche 95B.2 Macan Petrol 2.0L 245Bhp 2019-21

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.
