Information
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.
Fits:
Porsche 356 / 912
Sizes:
#1187 .393/.341L x 249/249D W/1.3 Rockers
#86 .423/.358L x 273/273D W/1.3 Rockers
#86-5 .420/.358L x 281/281D W/1.3 Rockers
#622 .435/.368L x 296/296D W/1.3 Rockers
#86a .435/.369L x 290/290D, Solid Lifters, Performance Street Cam
#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.
