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.
