Push-rod cam follower (also called a valve lifter) sits between the camshaft lobe and the push-rod inside the engine block. Its job is to transfer the camshaft’s rotating motion into vertical movement, which opens and closes the engine valves in precise synchronization with the crankshaft. Each push-rod cam follower must maintain exact geometry and surface hardness to operate silently and efficiently while withstanding intense pressure and friction.

Location: Between camshaft and push-rod in the valve train
Function: Transfers camshaft motion to operate intake/exhaust valves
Replacement Interval: During engine rebuild or when camshaft shows wear
Symptoms of Wear: Valve noise, timing loss, poor performance

Over time, cam followers experience wear due to:
•  Continuous metal-to-metal contact with the camshaft lobe
•  Inadequate lubrication or oil contamination
•  Heat cycling and surface fatigue
•  Pitting or flattening of the contact surface

A worn cam follower can lead to:
•  Valve train noise or ticking Inconsistent valve timing
•  Reduced engine performance
•  Accelerated camshaft wear

Replacing worn followers during engine rebuilds or camshaft service restores quiet operation, accurate valve timing, and protects the camshaft from further damage.

Replace the cam followers during any engine rebuild or camshaft replacement. They should also be renewed if valve train noise, irregular valve motion, or oil contamination is observed, or as a preventive measure during classic Porsche restorations and high-mileage servicing.

Push rod - cam follower. 
Cam Follower is a precision replacement part for the original Porsche cam-follower used in older 4-cylinder engines. It is intended to operate smoothly under valve train motion, providing reliable contact between camshaft and push-rod mechanism.
Sold each, 8 required per engine.

Fits:
Porsche 356 - All 
Porsche 912 

Diagram ref no 7

A cam follower is a small, hardened component that rides on a camshaft lobe and transfers the cam’s motion to the push-rod, lifter, or other valve train elements. In this application, the push-rod cam follower converts the rotating cam profile into linear motion, ensuring that valves open and close correctly. It must withstand high contact stresses, rotational friction, and lubrication demands while maintaining precise geometry.

Location: Engine top / valve train region, between camshaft and push-rod or lifter assembly.
Fits: Porsche 356 series and 912 engines (all years) that use push-rod overhead valve (OHV) layout.
Quantity: Typically 8 are used per engine (one per valve) in many Porsche 356 / 912 configurations.

Over time, cam followers wear, develop surface fatigue, or lose hardness, which can alter their contact profile. A worn cam follower leads to imprecise valve lift, increased wear of the cam lobe, noise in the valve train, reduced performance, and in extreme cases, damage to cam lobes or push-rods. Because the cam follower is a critical interface in the valvetrain, any deviation from correct shape or surface quality can lead to less efficient engine operation or failures.

When to replace:
•  During an engine rebuild, especially whenever the camshaft or valve components (push-rods, lifters) are serviced or replaced.
•  When valve train noise or knocking develops, which may hint at excessive follower wear or clearances.
•  If you measure wear on the cam lobes or get unusually fast wear on the valves, replace the followers proactively.
•  For preventive maintenance in classic Porsche engines, especially high-mileage or restored vehicles, replacing cam followers helps ensure longevity of the camshaft itself.

Cast Aluminium Bolt-On Valve Cover Upgrade Set

Upgrade your engine with this Bolt-On Valve Cover Set, manufactured from durable cast aluminium and supplied as a complete two-piece package with the required mounting parts and gaskets.

Fits:

• Porsche 914 (1970-1976) 1.7 / 2.0ltr
• Porsche 912E 4CYL 1976

Designed as a practical bolt-on upgrade, these cast aluminium valve covers provide a strong and durable replacement for the existing covers while giving the engine a clean, upgraded appearance.

With two valve covers, mounting hardware and gaskets included, the kit provides the essential components required for installation in one convenient package.

What Do Valve Covers Do?

Valve covers enclose and protect the upper valve train components while helping contain engine oil within the cylinder head assembly.

Their main functions include:

• Protecting valve train components from dirt and contamination
• Preventing engine oil from escaping
• Maintaining a sealed environment around the valve gear
• Supporting reliable engine operation
• Protecting internal components from external debris

A correctly fitted valve cover and gasket are essential for maintaining an effective oil seal.

Why Upgrade to Cast Aluminium Valve Covers?

Cast aluminium provides a strong and durable solution for replacing ageing or damaged original valve covers.

Benefits of upgrading include:

• Robust cast aluminium construction
• Improved durability
• Clean engine bay appearance
• Direct bolt-on installation
• New gaskets supplied
• Mounting components included
• Complete two-piece replacement set

This makes the kit particularly suitable for engine refurbishment, restoration and performance-focused builds.

Why Do Valve Covers and Gaskets Fail?

Valve covers are exposed to constant engine heat, vibration and repeated heating and cooling cycles. Over time, covers can become damaged or distorted, while the sealing gaskets gradually harden and lose their ability to maintain an effective seal.

Common problems include:

• Oil leaks around the valve cover
• Hardened or deteriorated gaskets
• Distorted sealing surfaces
• Cracked or damaged covers
• Damaged mounting points
• Previous over-tightening of mounting hardware

Oil visible around the valve cover or cylinder head area can indicate that inspection is required.

When Should They Be Replaced?

Replacement or upgrading should be considered when:

• Valve covers are damaged or distorted
• Persistent oil leaks are present
• Existing gaskets have deteriorated
• Carrying out an engine rebuild
• Restoring or refreshing the engine
• Upgrading to stronger cast aluminium components

Installing new gaskets at the same time helps provide a fresh seal and reduces the risk of leaks from reusing ageing sealing components.

Kit Includes

• 2 x cast aluminium valve covers
• 2 x Valve cover gaskets
• Mounting hardware parts
