This comprehensive timing chain overhaul kit includes the duplex timing chain along with guide rails, tensioner hardware and timing chain system components. Designed for Porsche 911 997 Turbo 3.6L M97.70 2007-2009. It ensures your timing drive system is fully refreshed.
Fits:
- Porsche 997 MK1 TURBO 2007-09
Diagram Ref No 23, 26, 29, 30, 31
What These Products Do:
- The timing chain ensures synchronicity between the crankshaft and camshafts (and sometimes intermediate shafts) so that the engine’s valves open and close at precisely the correct times.
- The chain drives these components; the guides/rails maintain correct chain path and tension, avoiding slack or mis‐alignment.
- Over time, chain wear, guide wear, tensioner fatigue or rail damage can allow the timing chain to “slacken” or develop play, which compromises timing accuracy, increases noise, and in worst cases can lead to catastrophic engine damage.
- The kit replaces all critical elements so the timing system returns to factory specification: fresh chain, guides, rails and related drive mechanism components.
Symptoms & When To Replace:
- Persistent rattling or clattering noise from the front of the engine (timing cover area) especially on cold start or idle — a common symptom of chain slack.
- Check engine light or fault codes related to camshaft timing, intermediate shaft, or variable valve timing — indicating potential timing chain or guide issues.
- Loss of power, rough running, misfiring or erratic engine behaviour — if timing is drifting due to chain wear/tensioner failure.
- High mileage engine or suspected wear: For performance engines, even if no overt symptoms yet, many recommend proactive replacement of timing system components when major work is being done.
- During major engine service (e.g., removal of timing cover, replacement of camshafts, front engine work) — since labour to access timing system is significant, replacing the kit at that time is efficient.
- When inspection reveals visible signs: worn chain links, elongated chain, cracked guide rails, damaged tensioner, excessive play in timing drive components.
Why Replacement Matters:
- Protects engine integrity: A failed timing chain or guide can lead to valve‐to‐piston contact, catastrophic engine damage, and huge repair cost — replacing this kit reduces that risk.
- Restores engine timing accuracy: A new chain/guide/rail set ensures valve timing is correct, delivering full engine performance, proper idle, smooth operation and correct response.
- Eliminates timing drive noise: Slack chain or failing guides often cause audible noise; fresh components restore quiet and refined engine behaviour.
- Cost-effective when open: Since accessing the timing chain system involves significant labour, replacing the full kit while you’re already under the timing cover saves rework later.
