The timing chain tensioner is designed to maintain correct chain tension in Porsche M96 and M97 engines. This hydraulic tensioner ensures the timing chain remains tight, properly aligned, and stable across all engine speeds, preventing chain slack, noise, and timing deviation.
Fits:
Porsche 986 Boxster 2.7L / 3.2L 2003 - 2004
with Engine codes: M96.23 / M96.24

with Engine codes M96.05 / M97.01
Diagram Ref No 33.
Built to original Porsche specifications, the tensioner uses controlled oil pressure to absorb chain vibration and compensate for thermal expansion, ensuring precise valve timing and smooth engine operation.
Over time, the timing chain tensioner can weaken internally, allowing the chain to develop slack and produce rattling noises, especially on start-up. A failing tensioner can cause timing drift, poor running, and accelerated wear of the guides and sprockets. If left unresolved, the chain may even skip a tooth, risking serious internal engine damage. Replacing the tensioner restores stable chain control, accurate timing, and long-term engine protection.
When to replace:
• You hear chain rattle, especially during cold start
• Fault codes or symptoms indicate timing deviation
• Engine runs rough, lacks power, or shows intermittent misfires
• Visible wear or oil leakage around the tensioner housing
• Chain guides have been replaced during an engine service
• Preventatively during M96/M97 engine rebuilds or high-mileage maintenance

Why replacement matters
Timing-chain systems wear over time: chains stretch or wear, guides and tensioners degrade, and components lose tension. This can result in:
• Chain slack, skipping or jumping - leading to timing misalignment, valve timing errors or even engine damage.
• Increased engine noise, rough idling or poor performance.
• Accelerated wear on camshafts, valves or pistons in severe cases.
A full replacement with this kit renews all critical timing components at once, restoring factory timing precision and long-term reliability - often more cost-effective than piecemeal repairs.
When to Replace
Consider replacing the entire timing chain kit if:
• You hear rattling, slapping or chain noise from the front of the engine, especially at cold start or idle.
• You detect timing-related performance issues - misfires, rough idle, loss of power, erratic valve timing.
• Oil contains metal shavings or debris indicating wear of guides or chain components.
• You are performing a major engine service or rebuild, or you are at high mileage / high load conditions.
• The vehicle’s service history is unknown or incomplete.

The kit includes:
1 x Camshaft
adjuster unit
1 x Securing bolt (single-use torque fastener)
Designed to meet OEM specifications, this kit ensures precise valve timing control and reliable engine performance.
What the Camshaft Adjuster Does
The camshaft adjuster is a key component of Porsche’s VarioCam variable valve timing system. It allows the engine control unit to adjust camshaft timing dynamically depending on engine speed, throttle input and load conditions.
By advancing or retarding valve timing, the camshaft
adjuster helps to:
- Improve low-end torque
- Enhance high-RPM power delivery
- Optimise fuel efficiency
- Reduce exhaust emissions
- Maintain smooth engine operation
The securing bolt clamps the adjuster firmly to the camshaft, ensuring accurate alignment and stable operation under high engine loads.
Why Camshaft Adjusters and Bolts Fail
Camshaft adjusters operate under high oil pressure and
constant rotational stress. Over time, they may fail due to:
- Internal wear of adjustment mechanisms
- Oil contamination or sludge buildup
- Loss of hydraulic pressure control
- High mileage wear Aggressive driving conditions
The securing bolts are often torque-to-yield fasteners designed for single use. Reusing old bolts can lead to insufficient clamping force, improper seating or loosening under load.
Common symptoms of failure include:
- Check engine light illumination
- Camshaft position or timing correlation fault codes
- Rough idle or hesitation
- Loss of power
- Rattling noise from the timing area
- Reduced fuel efficiency
In severe cases, incorrect cam timing can cause further engine damage if not addressed promptly.
Why You May Need This Camshaft Adjuster Kit
If your Porsche 958 Cayenne 4.8 V8 or 970 Panamera 4.8 V8 or 3.6 V6 is displaying camshaft timing faults, replacing both the adjuster and the securing bolt ensures a complete and reliable repair.
This kit is essential during:
- VarioCam repairs
- Timing chain service
- Cylinder head work
- Engine rebuilds
- Camshaft replacement
- Diagnosis of camshaft timing deviation codes
Installing a new adjuster together with a new bolt guarantees proper torque specification and long-term timing stability.
