Timing Chain.Genuine Porsche duplex timing chain for 911 997 Turbo/GT2 MKI / MKII 3.6L M97.70 2006-2011 – replaces stretched or worn chain to restore precise engine timing.

Diagram Ref No 29
What This Product Does:
- The timing chain transfers rotational motion from the crankshaft or intermediate shaft to the camshaft(s) (and/or to the secondary shaft) allowing valves to open and close in synchrony with piston movement.
- A “duplex” chain (two rows of links) provides greater strength and durability under the high loads and high engine speeds typical of a Porsche 911 performance engine.
- Because the chain drives critical timing, any slack, wear or movement will affect valve timing, ignition timing, engine management, and can result in noise, performance loss or engine damage.
- In this context, this chain is often replaced as part of a full timing drive overhaul (including guides, rails, tensioners) rather than alone.
Symptoms & When You Should Replace:
- Rattling or clattering noise from the front of the engine (timing cover area), often heard at idle or on start-up — typical of chain slack.
- Check engine light related to camshaft or timing chain position sensors, or codes showing timing deviation.
- Loss of engine power, mis-firing, rough running — could indicate timing drift due to chain wear.
- High mileage or older engine with original chain: preventive replacement recommended to avoid catastrophic failure.
- During major engine service (removing timing cover, replacing chains/guides) — because labour is high, replacing the chain proactively makes sense.
- If inspection reveals visible wear: elongated chain links, damaged chain guides or missing/broken tensioner components.
Why Replacement Matters:
- Protects the entire engine: A failed timing chain can lead to valve-to-piston contact, major damage and extremely costly repairs — replacing the chain is preventive.
- Restores proper timing & performance: A new chain ensures correct valve and ignition timing, helping engine run smoothly, powerfully and reliably.
- Eliminates noise & wear risk: Worn chains and guides cause noise and degrade timing drive integrity — a new chain reduces risk and improves sound.
- Cost-efficient when engine is opened: Since accessing the chain involves removing major parts (timing cover, possibly front of engine), replacing the chain while it’s open saves re-labour.

Description:
The four-valve technology is one of the sensitive parts of these otherwise robust engines: A regular replacement of the chain and its sliding elements is essential to avoid major damage. Combined with the sealing kit for the valve cover, you will receive all the parts you need to carry out the repair professionally.
Note:
For many vehicles over the years for cost reasons, only the upper shoe and the chain was changed. But even the lower shoe enters and becomes porous. Therefore, better anticipate the risk and take a look under the valve cover.
