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.
