The camshaft is one of the engine's most important internal components. Its precisely shaped lobes control the movement of the intake and exhaust valves through the associated valve-train components. Camshaft profile determines critical characteristics including valve lift, duration and timing, all of which influence cylinder filling, exhaust gas evacuation, combustion efficiency and engine performance.

What This Product Does:
  • Restore correct camshaft and valve-train operation.
  • Control the opening and closing of the intake and exhaust valves.
  • Maintain correct valve timing relative to crankshaft position.
  • Provide the required valve lift and duration.
  • Support efficient cylinder filling with the intake charge.
  • Allow effective evacuation of exhaust gases.
  • Maintain consistent valve operation across the engine.
  • Support smooth combustion and dependable engine performance.
  • Replace worn or damaged camshaft-related components.
  • Provide a coordinated solution for compatible engine rebuilds and repairs.
  • Restore valve-train functionality when correctly installed and timed.

Symptoms Of Wear Or Failure:
  • Ticking, tapping or abnormal valve-train noise.
  • Reduced engine power or acceleration.
  • Poor throttle response.
  • Rough or inconsistent idle.
  • Engine misfires.
  • Uneven performance between cylinders.
  • Difficulty maintaining correct valve clearances.
  • Repeated changes in valve adjustment.
  • Reduced valve lift.
  • Flattened or excessively worn cam lobes.
  • Pitting or scoring on camshaft surfaces.
  • Excessive wear of mating followers, lifters or rocker components.
  • Metallic particles in the engine oil or oil filter.
  • Abnormal camshaft journal wear.
  • Visible valve-train damage during engine disassembly.

Why Replacement Matters:

  • The camshaft directly controls the engine's valve movement. When a cam lobe becomes worn, its effective profile changes, potentially reducing how far or how long the corresponding valve opens.
  • Reduced valve lift or incorrect effective duration can restrict the amount of air and fuel entering the cylinder or interfere with the removal of exhaust gases. The result may be reduced power, rough running, poor throttle response and inefficient combustion.
  • Camshaft wear can also spread to associated valve-train components. A damaged cam lobe may accelerate wear of its mating follower, lifter or rocker component, while a damaged mating component can quickly deteriorate a replacement camshaft. Metallic debris produced by this wear can then circulate through the lubrication system and potentially damage other internal engine components.

As the engine rotates, precisely shaped lobes on each camshaft operate the corresponding valve-train components. The profile of these lobes determines valve lift, duration and timing, ensuring that the valves open and close at the correct points in the combustion cycle.

What This Product Does:
  • Control the opening and closing of the intake and exhaust valves.
  • Maintain correct valve timing relative to crankshaft position.
  • Determine valve lift through the profile of the camshaft lobes.
  • Control how long each valve remains open.
  • Transfer rotational movement through the valve train.
  • Help the cylinders receive the correct intake charge.
  • Support efficient evacuation of exhaust gases.
  • Help maintain smooth and consistent combustion.
  • Influence engine power, torque and throttle response.
  • Maintain coordinated valve operation across the engine.
  • Replace worn, scored, pitted or damaged original camshafts.
  • Provide OE-style replacements for compatible Porsche engine applications.

Symptoms Of Wear Or Failure:
  • Ticking, tapping or abnormal valve-train noises.
  • Reduced engine power or acceleration.
  • Rough or inconsistent engine operation.
  • Engine misfires.
  • Uneven performance between cylinders.
  • Difficulty maintaining correct valve clearances.
  • Repeated changes in valve adjustment.
  • Reduced valve lift.
  • Flattened or excessively worn camshaft lobes.
  • Scoring, pitting or surface deterioration on the lobes.
  • Abnormal wear on rocker arms or other cam-contact components.
  • Excessive camshaft journal wear.
  • Metallic particles in the engine oil or oil filter.
  • Visible camshaft damage during an engine rebuild.

Why Replacement Matters:

  • The camshaft determines when and how far the engine's valves open. Even relatively small changes caused by cam lobe wear can affect how efficiently a cylinder draws in its intake charge and expels exhaust gases.
  • A worn cam lobe may provide less valve lift than intended. This can restrict engine breathing and contribute to reduced power, poor throttle response, rough running or uneven performance between cylinders.
  • Camshaft wear can also affect associated valve-train components. Damaged contact surfaces may accelerate wear of rocker arms or other components that operate against the camshaft. Metal particles generated by this deterioration can circulate through the lubrication system and contribute to further internal engine wear.
  • Severe camshaft or journal damage may also compromise smooth camshaft rotation and correct valve timing. Continued operation can turn a valve-train problem into a more extensive and expensive engine repair.
