Information
Timing chain tensioner. Cyl. 4-6. RIGHT.
This OE Match timing chain tensioner is a direct replacement for the original Porsche component fitted to the right-hand cylinder bank (cylinders 4–6). It maintains proper tension on the engine timing chain to ensure precise camshaft timing and smooth engine operation.
Fits:
Porsche 997.1 Turbo / GT2 2007 - 2009
Porsche 997.2 Turbo / GT2 2010 - 2013
Porsche 997 GT3 2007 - 2011
Diagram ref no 10
The timing chain tensioner maintains the correct tension on the engine timing chain, ensuring accurate synchronisation between the crankshaft and camshafts. This helps the engine run smoothly, prevents chain slack, and protects against timing-related engine damage.
Function
• Maintains correct timing chain tension
• Prevents chain slack and timing fluctuation
• Ensures accurate camshaft and crankshaft synchronisation
• Reduces timing chain vibration and noise
• Supports reliable high-performance engine operation
Position: Right side / cylinders 4–6
OE reference: 99710506271
Supersedes: 99710506270, 95910505203
Recommended gasket/seal: 99610517270 (sold separately)
Quantity required: 1 per engine side
Over time, timing chain tensioners can wear internally or lose hydraulic pressure efficiency. A failing tensioner may cause timing chain noise, inaccurate valve timing, or excessive chain movement, potentially leading to severe engine damage. Replacing a worn tensioner restores correct timing stability, protects internal engine components, and maintains performance reliability.
When to replace
• Rattling noise from timing chain area during startup
• Timing-related fault codes or irregular engine timing
• During engine rebuild or timing system service
• Excessive timing chain slack detected
• Oil leakage around tensioner housing

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

Common issues or symptoms:
Rough idle / misfires: Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires.
Reduced engine performance: Loss of power or hesitation at certain RPMs can be linked to improper camshaft adjustment Check Engine Light (CEL), often triggered when the engine control unit (ECU) detects misalignment or malfunction in camshaft timing - very common with actuator failure.
Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires Diagnostic Trouble Codes (DTCs): Codes like P0010, P0011, P0012, P0013, P0014 often point to camshaft actuator or timing issues. They indicate conditions such as stuck timing advance/retard, or electrical faults in the actuator circuit Failure Causes: Oil contamination or sludge can clog the actuator, impairing function. Electrical problems such as wiring degradation or poor connector contact can impede correct activation
Diagnostic & repair advice check oil quality and change intervals - fresh, clean oil helps prevent buildup that hampers actuator performance scan for and interpret fault codes using an OBD-II scanner to pinpoint actuator failure or control circuit issues Inspect connectors and wiring for corrosion or looseness Replace defective solenoid(s) with OEM or high-quality equivalents if internal stick or mechanical failure is suspected.

NOTE: For the 2001 model year, Porsche replaced the intermediate shaft's roller-type (duplex) chain with a tooth-type chain. This listing is for the later tooth-type chain and is not compatible with earlier engines equipped with the roller-type chain.
While unlikely, it's possible that an earlier engine may have been rebuilt and upgraded to use the newer chain design. For this reason, Design 911 strongly recommends confirming which type of chain your engine uses before placing an order. To assist with identification, our product images include a helpful comparison between the roller-type (duplex) chain and the tooth-type chain.
