Restore dependable valve-train operation and provide the correct working interface for a compatible camshaft with this OE Match Set of Web Cam Lifters, reference WC-NL-174. Designed for use in compatible engine builds, these lifters—also known as cam followers or tappets—transfer the movement of the camshaft through the valve train, allowing the intake and exhaust valves to open and close correctly.
Fits:
Porsche 356 / 912
Lifters operate directly against the camshaft lobes and are subjected to continuous mechanical loading, friction, and high engine temperatures. Their condition and compatibility with the camshaft are therefore critical to valve-train reliability. A correctly matched lifter maintains consistent contact with the cam lobe, helping preserve the intended camshaft profile and accurate valve operation.
What This Product Does:
- Follows the profile of the rotating camshaft lobes.
- Transfers camshaft movement through the valve train.
- Helps control the opening and closing of the intake and exhaust valves.
- Supports correct valve lift and timing.
- Provides a critical contact surface between the camshaft and valve train.
- Helps maintain consistent valve-train operation.
- Supports smooth and dependable engine performance.
- Replaces worn, pitted, scored, or damaged lifters.
- Provides a suitable solution for compatible engine rebuilds and camshaft installations.
Symptoms Of Wear Or Failure:
- Ticking, tapping, or clicking from the valve train.
- Increasing valve-train noise with engine speed.
- Difficulty maintaining correct valve clearances.
- Repeated changes in valve adjustment.
- Reduced engine power or performance.
- Rough or inconsistent engine operation.
- Reduced valve lift due to component wear.
- Pitting or scoring on the lifter faces.
- Concave or uneven wear on the lifter contact surfaces.
- Visible wear or damage to corresponding camshaft lobes.
- Metallic particles in the engine oil.
- Abnormal lifter wear discovered during engine disassembly.
Why Replacement Matters:
- Lifters are critical to both valve operation and camshaft durability. The camshaft and lifter contact surfaces operate together under substantial mechanical pressure, and excessive wear to either component can alter the intended valve lift and timing.
- A worn, pitted, or incorrectly matched lifter may damage the corresponding camshaft lobe. As the surfaces deteriorate, metal particles can enter the engine oil and circulate through the lubrication system, potentially contributing to further internal engine wear.
- A badly worn lifter or cam lobe can also reduce valve lift, affecting cylinder filling and exhaust gas flow. This may result in reduced performance, rough running, and inefficient combustion.
- Correct installation is particularly important when fitting replacement lifters. The condition of the camshaft must be inspected carefully, and the lifters must be compatible with the specific camshaft being used. Installing new lifters against an unsuitable or severely worn camshaft may result in rapid wear and premature failure.
- Replacing worn or unsuitable components with the correct OE Match Web Cam Lifters WC-NL-174 helps restore consistent valve-train movement, correct camshaft operation, and dependable engine performance when correctly matched and installed.

Manufactured from high-strength, heat-treated steel with precision-machined contact surfaces, the rocker arm is engineered to withstand constant reciprocating movement, high engine speeds and extreme operating temperatures. Designed for direct OE-style installation, it provides precise alignment with the camshaft and valve train components, making it ideal for engine rebuilds, cylinder head repairs and preventative maintenance.
What This Product Does:
- Transfers camshaft movement to the engine valves.
- Controls the opening and closing of the intake or exhaust valves.
- Maintains accurate valve timing and lift.
- Supports efficient combustion and engine performance.
- Reduces friction within the valvetrain assembly.
- Ensures smooth and reliable valve operation.
- Restores factory valvetrain performance.
- Forms an essential part of the engine valve train assembly.
Symptoms Of Wear Or Failure:
- Ticking or tapping noises from the top of the engine.
- Engine misfires.
- Reduced engine performance.
- Rough idle.
- Loss of power during acceleration.
- Excessive valvetrain wear.
- Uneven valve operation.
- Increased engine vibration.
- Metal particles found during engine servicing.
- Engine fault codes relating to valve timing or cylinder performance.
Why Replacement Matters:
- The rocker arm is subjected to continuous high-speed movement, heavy contact loads and constant lubrication cycles every time the engine operates. Over time, the contact surfaces, pivot points or roller mechanism (where applicable) can wear, reducing the precision of valve operation and increasing stress on the camshaft and valves.
- A worn or damaged rocker arm can prevent the valves from opening and closing correctly, leading to reduced engine performance, poor fuel economy, rough running and accelerated wear of other valvetrain components. If left unresolved, severe wear can result in valve train failure and costly engine repairs.
- Replacing a worn rocker arm restores accurate valve operation and ensures the engine continues to deliver smooth, efficient performance. The OE Match Rocker Arm is manufactured to OE standards using premium-quality materials, providing factory-style fitment, exceptional durability and long-lasting reliability, making it the ideal choice for Porsche engine repairs, rebuilds and preventative maintenance.

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.
