What This Camshaft Alignment Tool Does
This tool set enables:
- Precise positioning of all four camshafts on 3.6-litre Porsche turbo and GT2 engines
- Secure locking of cams during chain replacement and timing setup
- Accurate timing retention, preventing rotation or timing mismatch
- Correct alignment during cam phaser and chain tensioner servicing
- Professional-grade engine rebuilds with consistent timing accuracy
- Simplified installation via two specialised wrenches and pre-tensioner tools
Accurate camshaft timing ensures optimal engine performance, combustion efficiency, and long-term reliability.
Tool Set Components
- Two long camshaft wrenches (two thicknesses) for easy access and leverage
- Two cam chain pre-tensioner tools, ensuring chain tension during timing setup
- Locking fixtures for all four camshafts to maintain exact alignment
Designed for safe, efficient and repeatable timing chain replacement.
Compatible with engine types
M97/70S M97/70 M96/70S M96/70E
Why Timing Components Fail on Mezger-Based Porsche Engines
These high-performance engines are subjected to extreme
loads, track usage, and high temperatures. Common failure points include:
- Timing chain stretch affecting cam synchronisation
- Worn cam chain guides causing slack and deviation
- Tensioner wear leading to startup rattles or timing drift
- Improper timing after previous repairs when incorrect tools were used
- Heat cycling, causing expansion and contraction of timing components
- Cam phaser wear, impacting valve timing accuracy
Symptoms often include: misfires, timing-related fault codes, loss of boost response, uneven idle, or unusual mechanical noise.
Why You Should Replace or Use This Camshaft Alignment Tool
A precision camshaft alignment tool ensures:
- Perfect synchronisation of all four camshafts Safely maintained timing during chain replacement
- Protection from costly piston-to-valve interference
- Accurate VVT/cam phaser alignment
- Reduced risk of engine damage during rebuilds
- Professional-standard timing result
- Confidence when working on high-value Porsche Turbo and GT2 engines
This tool is essential for anyone servicing or rebuilding Mezger-engined 911 models.

OEMatch Specialist Tools — Fit, Function, Confidence
Specialist tools are central to accurate Porsche engine work, from initial strip-down to final torque checks. OEMatch focuses on Porsche applications, supporting detailed rebuilds, diagnosis and assembly so work can be carried out methodically on both classic and modern engines.
- Engine rebuild fixtures and holding tools
- Measurement and inspection tools for critical clearances
- Timing, locking and alignment tools for Porsche applications
- Tools to aid safe removal and installation of internal components
- Equipment to support diagnostic checks during and after assembly
Understanding OEMatch Specialist Tools
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original specialist tools. OE (Original Equipment) refers to parts matching original specifications for the specialist tools and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM specialist tools engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Many owners search for genuine or OEM specialist tools; these are direct-fit alternatives designed to match the original form, fit and function. Porsche engines rely on tight tolerances, controlled clamping loads and model-specific procedures, so using equipment designed around these requirements helps maintain accuracy when dismantling, measuring and rebuilding. OEMatch concentrates on Porsche-focused tools that assist with measurement, timing, installation and verification tasks so work can be completed in a controlled, repeatable way.
- Support for precise measurement of bores, deck height, ring gaps and valve clearances
- Purpose-made fixtures for crankshaft, piston, liner and bearing handling
- Timing aids for camshaft alignment and intermediate shaft positioning
- Tools that reduce the likelihood of damage during removal and refitting
- Equipment that assists with even torque application on fasteners and critical joints
- Support for leak-down, compression and similar diagnostic checks
Why Specialist Tools Wear and Fail
- Metal fatigue from repeated loading during pressing, pulling or clamping
- Stripped or worn threads where tools are frequently tightened and released
- Corrosion or surface degradation from moisture, cleaning fluids or workshop chemicals
- Heat exposure when working close to exhaust components or cylinder heads
- Loss of calibration on measurement and torque tools over extended use
- Damaged contact faces or adaptors due to misuse or excessive force
- Contamination from swarf and workshop debris affecting accuracy and operation
The Importance of Replacing with OEMatch Specialist Tools
Refreshing worn equipment or adding Porsche-focused tools from OEMatch helps support accurate, consistent working practices during engine rebuilds. Where generic tools may not match Porsche-specific geometry or access, dedicated items can help reach critical fasteners, support assemblies correctly and provide clear measurements. For owners and workshops working on restoration, top-end repairs or full rebuilds, this contributes to controlled assembly procedures and supports long-term engine reliability.
- Support for accurate measurement of critical Porsche engine dimensions
- Improved control when installing and removing internal components
- Better torque and alignment consistency across repeated jobs
- Tools chosen around common Porsche engine procedures and layouts
- Support for safer handling of components during demanding workshop tasks
- Potential time savings when performing complex operations repeatedly
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
