The kit includes:
2 x Camshaft adjuster unit
2 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.
