Information
Camshaft.
Maintain precise valve timing and dependable engine performance with this OE Match Camshaft, manufactured as a direct replacement. Produced to OE-style specifications, this camshaft is engineered to control the opening and closing of the engine's intake and exhaust valves, ensuring efficient combustion, smooth power delivery, and reliable engine operation.
Fits:
The camshaft is one of the most critical components within the valve train, operating continuously under high loads and engine speeds. Over time, camshaft lobes, bearing journals, or mating surfaces can become worn through insufficient lubrication, high mileage, or contamination, resulting in reduced valve lift, poor engine performance, and increased mechanical noise. Replacing a worn camshaft restores correct valve timing and lift, helping to return the engine to its intended performance. This OE Match component is ideal for routine maintenance, engine rebuilds, repairs, and Porsche restoration projects.

Camshaft.
Restore or upgrade valve-train operation with this OE Match Camshaft, available under references WC-05-572, WC-05-112, WC-05-582, WC-05-012, WC-05-022, and WC-05-222. The camshaft is one of the engine's most important valve-train components, controlling when and how far the intake and exhaust valves open during each combustion cycle.
Please Note New cams should be installed using new lifters and proper assembly lube, or Severe damage may occur.

#86b .500/425L x 290/290D W/1.3 Rockers
As the camshaft rotates, its precisely shaped lobes act on the lifters or followers, transferring movement through the valve train to operate the intake and exhaust valves. The profile of each cam lobe determines critical characteristics including valve lift, duration, and timing, which influence cylinder filling, exhaust gas evacuation, engine response, torque delivery, and overall performance.

As the camshaft rotates, its precisely shaped lobes act on the lifters or followers, transferring movement through the valve train to operate the intake and exhaust valves. The profile of each cam lobe determines critical characteristics including valve lift, duration, and timing, which influence cylinder filling, exhaust gas evacuation, engine response, torque delivery, and overall performance.
What This Product Does:
- Controls the opening and closing of the engine's intake and exhaust valves.
- Determines valve timing relative to crankshaft position.
- Controls valve lift through the shape and height of the cam lobes.
- Determines how long the valves remain open through camshaft duration.
- Works with lifters or cam followers to operate the valve train.
- Helps control how efficiently the cylinders fill with the air/fuel mixture.
- Supports efficient evacuation of exhaust gases.
- Influences engine torque, power delivery, throttle response, and operating characteristics.
- Maintains coordinated valve operation throughout the engine cycle.
- Replaces a worn, damaged, or unsuitable existing camshaft.
- Provides options for compatible standard, rebuilt, or performance-oriented engine configurations.
Symptoms Of Wear Or Failure:
- Ticking, tapping, or abnormal valve-train noise.
- Reduced engine power or acceleration.
- Rough or inconsistent engine operation.
- Difficulty maintaining correct valve clearances.
- Repeated changes in valve adjustment.
- Reduced valve lift.
- Uneven engine performance between cylinders.
- Misfires or poor combustion.
- Excessive wear or flattening of individual cam lobes.
- Pitting, scoring, or surface damage on camshaft lobes.
- Abnormal wear on the lifters or cam followers.
- Metallic particles in the engine oil.
- Visible camshaft damage discovered during an engine rebuild.
- The camshaft directly controls the movement of the engine's valves, making its condition fundamental to compression, combustion, and engine performance. If a camshaft lobe becomes worn or flattened, the corresponding valve may no longer open to the intended height or remain open for the correct duration.
- Reduced valve lift can restrict the amount of air and fuel entering the cylinder or prevent exhaust gases from leaving efficiently. This may lead to reduced power, poor throttle response, rough running, and inefficient combustion.
- Camshaft and lifter condition are also closely related. A damaged camshaft lobe can rapidly wear the corresponding lifter, while an unsuitable or damaged lifter can accelerate camshaft wear. Metal produced by this wear can circulate through the engine lubrication system and potentially damage other internal components.
- Correct camshaft selection is particularly important with performance-oriented profiles. Changes in lift, duration, and timing can affect valve-to-piston clearance, valve-spring requirements, rocker geometry, compression characteristics, idle quality, torque delivery, and usable engine-speed range. The complete engine combination must therefore be considered rather than selecting a camshaft solely by reference or appearance.

- 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.
