Engine Timing Chain Kit.
This timing chain kit is designed for Porsche 996 Turbo 3.6L M96.70 engines requiring replacement of the timing chain and associated components. The kit  includes the timing chain, guides/rails and other essential timing drive hardware.

This overhaul kit ensures your engine’s timing system is brought back to proper specification — chain, guides, rails, tensioning path — all refreshed in one package.

Fits:

• Porsche 996 TURBO 2000-05

Diagram Ref No 18, 21, 23, 24, 25

What These Products Do:

• The timing chain system synchronises the crankshaft and camshafts (and sometimes intermediate shafts) so that valves open/close at the correct times relative to piston position.
• The chain itself drives the cam from the crank or intermediate shaft. Guides/rails ensure the chain runs in the correct path, stays under tension, and minimises noise and wear.
• Over time, the chain can stretch, guides can wear or fracture, tensioners can lose preload — which leads to timing slack, chain noise, and in worst cases mis-timing or catastrophic engine damage.
• A full kit replacing the chain and guides resets the timing system back to proper specification — chain path, tension, alignment — thereby restoring performance, reliability, and longevity of the engine.

When You Should Consider Replacement:

• You hear rattling or clattering from the front of the engine (timing cover area) during start-up, idle or under load — a classic sign of chain slack.
  
• You experience poor engine performance, rough running or misfires linked to timing errors.
  
• The engine has high mileage or long service history with original timing components — wear is cumulative and replacing early can prevent failure.
  
• On inspection you find worn guides/rails (cracked plastic, split surfaces) or visible chain slack.
• You catch related diagnostic trouble codes (DTCs) for camshaft timing or intermediate shaft etc.

Why Replacement Matters:

• Protects the engine: Timing chain failure can lead to valve-to-piston contact, major engine damage and huge cost. Replacing the chain system early is preventive.
  
• Restores correctly timed operation: With new chain/guides, your cam/valve timing is returned to spec; the engine runs smoother, more reliably, and with full power.
  
• Eliminates noise & improves reliability: Worn guides or slack chain produce unacceptable noise and indicate impending failure. Replacing resolves these.
  
• Cost-effective while open: Major labour is already required to access the timing chain; replacing only part of the system risks repeated labour later.
