Camshaft (set of 2). Porsche 911S (67-73) Mechanical Injection  ❭  WC-05-062

Camshaft (Set of 2).
Restore or upgrade accurate valve-train operation with this OE Match Camshaft Set, reference WC-05-062, supplied as a set of 2 camshafts for compatible engine applications. Camshafts are critical valve-train components responsible for controlling precisely when and how far the intake and exhaust valves open and close throughout the engine's operating cycle.

Fits:
Porsche 911S (67-73) Mechanical Injection

Size:
#149i/149e .450/.400L 284°/256°D

Made of high quality billet blank Web cams have been Race proven for years, and provide reliable HP at all Power ranges.

As each camshaft rotates, its precisely machined lobes operate the corresponding followers, lifters, or other valve-train components. The shape of each lobe determines important characteristics including valve lift, duration, and timing, directly influencing cylinder filling, exhaust gas evacuation, combustion efficiency, torque delivery, and engine performance.

What This Product Does:

• Includes 2 camshafts for compatible engine applications.
• Controls the opening and closing of the intake and exhaust valves.
• Determines valve timing relative to crankshaft position.
• Controls valve lift through the shape of the camshaft lobes.
• Determines how long the valves remain open through camshaft duration.
• Works with the followers or lifters to operate the valve train.
• Helps control efficient cylinder filling.
• Supports effective evacuation of exhaust gases.
• Influences torque, power delivery, throttle response, and overall engine characteristics.
• Helps maintain coordinated valve operation across the engine.
• Replaces worn, damaged, or unsuitable existing camshafts.
• Provides a matched set for compatible engine rebuilds and performance applications.

Symptoms Of Wear Or Failure:

• Ticking, tapping, or abnormal valve-train noise.
• Reduced engine power or acceleration.
• Rough or inconsistent engine operation.
• Misfires or uneven cylinder performance.
• Reduced valve lift.
• Difficulty maintaining correct valve clearances.
• Repeated changes in valve adjustment.
• Flattened or excessively worn camshaft lobes.
• Pitting, scoring, or surface damage on the lobes.
• Excessive wear on followers or lifters.
• Metallic particles in the engine oil.
• Abnormal camshaft journal or bearing wear.
• Visible camshaft damage discovered during engine disassembly.

Why Replacement Matters:

• Camshafts directly control the movement of the engine's valves, making their condition fundamental to correct combustion and engine performance. A worn or damaged camshaft lobe can reduce the amount a valve opens or alter its effective opening duration, preventing the engine from breathing as originally intended.
• Reduced or inconsistent valve lift can restrict airflow into the cylinders or interfere with exhaust gas evacuation. This may result in reduced power, rough running, poor throttle response, misfires, or inefficient combustion.
• Camshaft and follower condition are also closely related. A damaged camshaft surface can rapidly wear the corresponding follower, while a damaged or unsuitable follower can accelerate camshaft lobe wear. Metallic debris generated by this wear can circulate through the lubrication system and potentially affect other internal engine components.
• Because WC-05-062 is supplied as a set of two camshafts, replacing the required components together helps provide consistent valve-train operation across the engine. Correct timing and synchronisation of both camshafts are essential during assembly.
