Timing chain set camshafts for PORSCHE 996 3.4L Carrera 986 2.5L 2.7L 3.2L 


oematch

This timing chain kit includes the timing chains for the camshaft and intermediate shaft, as well as the slide and tension rails.

Due to the complex design with an intermediate shaft and two overhead camshafts, the water boxers of the modern Porsche 911 Carrera and Boxster have a variety of chains and slide rails. These vary depending on the displacement or model year, even within a series.

The chain guides were slightly changed between the 3.4L and 3.6L Carrera engines from 2001 to 2002. The engines of the 911 turbo and GT models, however, are based on the proven 911 technology from the previous models. The timing chains as well as slide rails and tensioning rails for the valve control are fundamentally different.

Fits: 

  • Porsche Boxster 986 2.5L 1997-99
  • Porsche Boxster 986 2.7L 1999-02
  • Porsche Boxster S 986 3.2L 1999-02

Comprehensive Engine Timing Chain Kit for M96 Engines

Restore the integrity of your M96 engine’s timing system with this complete timing chain kit. Early-generation M96 engines are equipped with five timing chains—this kit replaces all chains along with the associated guides, tensioners, and hardware for a full system refresh.

Note: If the intake-to-exhaust camshaft timing chain tensioners require replacement, use part numbers 99610505158 and 99610505358.

What is an Engine Timing Chain?

The timing chain is a vital component in an internal combustion engine, responsible for synchronizing the rotation of the crankshaft and camshafts. This precise coordination ensures that engine valves open and close at the correct times during each cylinder’s intake and exhaust strokes, allowing for smooth performance and efficiency.

While designed to last the lifetime of the engine, timing chains can wear, stretch, or become damaged. A worn chain can alter engine timing, strain the tensioners, and, if left unaddressed, lead to catastrophic engine damage and costly repairs. 

Signs of Timing Chain Kit Failure

Noise: A failing timing chain often produces a rattling or slapping noise, particularly noticeable at startup, idle, or during acceleration.

Reduced Performance: Stretched or worn chains can disrupt engine timing, resulting in sluggish acceleration, reduced power, or poor overall performance.

Product Information
Product Information
Actuator Camshaft. A solenoid component for the Variable Camshaft Timing (VarioCam Plus) system, used to adjust camshaft timing for optimal performance. Serves the front (intake/exhaust timing) of the VarioCam system, typically requiring two units per engine (one per bank)


Common issues or symptoms: 

Rough idle / misfires: Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires 

Reduced engine performance: Loss of power or hesitation at certain RPMs can be linked to improper camshaft adjustment Check Engine Light (CEL), often triggered when the engine control unit (ECU) detects misalignment or malfunction in camshaft timing — very common with actuator failure

Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires Diagnostic Trouble Codes (DTCs): Codes like P0010, P0011, P0012, P0013, P0014 often point to camshaft actuator or timing issues. They indicate conditions such as stuck timing advance/retard, or electrical faults in the actuator circuit Failure Causes: Oil contamination or sludge can clog the actuator, impairing function. Electrical problems such as wiring degradation or poor connector contact can impede correct activation 

Diagnostic & repair advice check oil quality and change intervals — fresh, clean oil helps prevent buildup that hampers actuator performance scan for and interpret fault codes using an OBD-II scanner to pinpoint actuator failure or control circuit issues Inspect connectors and wiring for corrosion or looseness Replace defective solenoid(s) with OEM or high-quality equivalents if internal stick or mechanical failure is suspected.

About Chains & Tensioners

Precision Timing Chains & Tensioners – Engine Synchronisation and Reliability for Porsche Models

The timing chain system is one of the most critical components of a Porsche engine, ensuring perfect synchronisation between the crankshaft and camshafts. This precise coordination allows valves to open and close at the right moment, maintaining smooth power delivery, fuel efficiency, and long-term engine health.

At Design911, we supply a comprehensive range of precision-engineered timing chains, guides, and hydraulic tensioners designed to meet or exceed manufacturer performance standards. Each component is manufactured from high-strength materials for exceptional wear resistance and durability — vital for high-revving, performance-oriented Porsche engines.

What Do Timing Chains and Tensioners Do?

A timing chain connects the crankshaft to the camshafts, ensuring accurate valve timing. The tensioner keeps the chain taut to prevent slack, vibration, or noise, maintaining precise timing under all load conditions.

Core Functions:

  • Synchronise engine timing between the camshaft and crankshaft.
  • Maintain valve timing accuracy for optimal combustion and power.
  • Prevent chain slack and noise through hydraulic or spring-loaded tensioning.
  • Ensure long-term reliability in both performance and everyday driving.

Together, these components preserve the exacting standards of Porsche engine operation — vital for both power and longevity.

Why Do Timing Chains and Tensioners Fail?

Over time, wear, oil degradation, and heat cycles can cause timing components to deteriorate. When neglected, they may stretch, seize, or lose tension — leading to severe engine damage.

Common Causes of Failure Include:

  • Chain stretch or elongation, resulting in timing misalignment.
  • Worn or leaking hydraulic tensioners, causing chain rattle on start-up.
  • Contaminated or degraded engine oil, accelerating wear.
  • Broken chain guides from heat stress or material fatigue.
  • Insufficient oil pressure, reducing hydraulic tensioner performance.

A failing timing chain system can lead to poor performance, rough idling, check-engine lights, or — in extreme cases — catastrophic valve-to-piston contact.

Why Replace with Performance-Grade Timing Components?

Replacing aging timing components with manufacturer-quality parts ensures reliable valve timing, smoother operation, and peace of mind.

Key Benefits:

  • Restores precise valve timing for peak performance and efficiency.
  • Prevents engine noise and vibration caused by chain slack.
  • Protects against catastrophic engine damage due to chain failure.
  • Constructed from heat-treated, high-grade steel for long service life.
  • Engineered to match original timing profiles for Porsche engines.
  • Perfect fitment for classic air-cooled and modern water-cooled models.

Whether performing preventive maintenance or a complete rebuild, these timing chains and tensioners deliver race-ready reliability with road-tested durability.

Highlights:

  • Precision-engineered timing chains, guides, and tensioners for Porsche engines.
  • Restores timing accuracy and eliminates start-up rattle or misfire issues.
  • Built from heat-treated alloy steel for maximum longevity.
  • Hydraulic and mechanical tensioners available for various Porsche models.
  • Ideal for performance rebuilds and preventative maintenance.
  • Compatible with air-cooled and water-cooled Porsche engines.
