99710506271/1
Product Information
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
