Camshafts
By OE Match
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 356 1950-55
- Porsche 356A 1955-59

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

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.

OEMatch Camshafts — Fit, Function, Confidence
For Porsche models, OEMatch Camshafts components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types
- Standard replacement camshafts
- Performance-profile camshafts
- Restoration-fit camshafts
Understanding OEMatch Camshafts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original camshafts.
OE (Original Equipment) refers to parts matching original specifications for the camshafts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM camshafts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Camshafts control valve timing, lift and duration to regulate how air and fuel enter and exhaust gases leave the combustion chambers. Correct cam timing supports efficient combustion, smooth idling and predictable throttle response. OEMatch aims to keep Porsche vehicles on the road and catalogs over 4,000 part numbers with more than 8,700 OE cross-references to support repairs, rebuilds and restorations.
Benefits Include
- Restores valve timing accuracy and smooth engine operation
- Improves throttle response and power delivery where matched to engine spec
- Precision-machined surfaces support wear resistance and consistent timing
Why Camshafts Wear and Fail
- Oil starvation causing friction and surface wear
- Excessive heat or poor lubrication degrading cam lobes
- Incorrect timing-belt or chain tension leading to misalignment or damage
- Contaminated oil introducing abrasive particles into the valvetrain
- Mechanical fatigue from extended mileage or intensive use
The Importance of Replacing with OEMatch Camshafts
Replacing worn camshafts restores the engine’s valve timing and combustion stability, which helps recover lost performance and reduces the risk of further valvetrain damage. OEMatch supplies items selected for Porsche applications and documented with cross-references to support restorations, engine rebuilds and performance tuning projects. Using correct-fit camshafts reduces the need for additional machining or modifications and helps preserve engine reliability.
Advantages
- Direct-fit alternatives made to original-spec dimensions and tolerances
- Suitable for restorations, rebuilds and performance tuning when fitted to correct engine specifications
- Parts supplied with documented cross-references to support fitment and selection
Support & Advice
These items affect critical engine timing. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and where specified.
