Information
Camshaft timing chain.
Timing chain from the intermediate shaft to the heads.
Sold each, Two chains are typically required per engine, as each bank uses its own camshaft timing chain.
Fits:
Porsche 996 Carrera 3.6L 2002 - 2004
Porsche 987 Boxster / Boxster S 2005 - 2008
Porsche 987C Cayman / Cayman S 2005 - 2008
Porsche 997 Carrera 3.6L / S 3.8L 2005 - 2008 COUPE / CABRIO
Diagram ref no. 26
The timing chain transfers rotational movement through the engine’s timing system so the camshafts open and close the intake and exhaust valves at the correct moment in the combustion cycle. Accurate synchronization between the crankshaft and camshafts is essential for optimal engine performance, efficiency and reliability.
Replacing worn or stretched timing chains helps maintain correct valve timing and prevents potential engine damage caused by timing inaccuracies.
Function
• Engine Timing Synchronisation: Links the intermediate shaft and camshafts
• Valve Control: Ensures intake and exhaust valves operate at precise timing intervals
• Durability: Designed to withstand continuous high-speed engine operation
• Direct Replacement: OE Match construction ensures correct fit and performance
Timing chains operate continuously under high load and temperature inside the engine. Over time they may stretch or wear, which can lead to inaccurate valve timing, engine noise, or performance loss. Installing a new OE Match timing chain helps maintain precise engine timing, ensures smooth operation of the valve train and protects critical engine components from premature wear.
Consider replacing the timing chain when:
• Performing a major engine rebuild
• Servicing the timing system or chain tensioners
• Experiencing timing chain noise or rattle
• High-mileage engine maintenance

Information
Chain guide rail.
This guide rail ensures the timing chain follows the correct path, maintaining chain alignment and tension over the life of the engine. The guide is engineered to resist wear from chain contact, vibration, thermal expansion and age. It installs into the existing timing cover without modification. It is used on the left/right-hand / lower side (depending on engine layout) and works in conjunction with the chain tensioners and other guide rails to keep valve timing accurate and engine operation smooth.
Fits:
Porsche 996 Turbo 2001 - 2005
Porsche 996 GT3 2000 - 2005
Porsche 997 Turbo 2007 - 2011
Porsche 997 GT3 2007 - 2011
Diagram ref no 21
Ideal for engine rebuilds, timing-chain replacements, or preventive maintenance on high-mileage engines.
This chain guide rail:
• Guides the timing chain to follow the correct path between crankshaft, camshafts, and intermediate shafts - ensuring synchronised valve timing.
• Maintains chain tension and alignment under load and throughout thermal cycles, preventing chain slippage or jumping that could damage the engine.
• Reduces noise, rattles, and wear that occur when the chain rubs against incorrect or worn surfaces.
• Serves as a critical component for overall engine longevity and reliability, especially in high-mileage or performance-oriented engines.
Timing-chain guide rails wear over time due to constant metal-to-plastic/rubber contact, heat, and vibration. A worn guide rail can lead to:
• Chain misalignment, slippage or jumping - risking engine timing errors, valve-to-piston contact, or catastrophic engine damage
• Excessive timing noise, rattling, or vibration
• Premature wear on chain, sprockets, and tensioners - leading to costly repairs.
Replacing with a correctly spec’d guide rail restores proper chain pathing, prolongs timing-system life, and helps avoid severe engine damage.
