Engine Timing Kit. Porsche 981 Cayman GT4 / 718 Cayman GT4

Complete Engine Timing Tool Set for Porsche 981 Cayman GT4 & 718 Cayman GT4 – Precision Tools for High-Performance Flat-Six Engines

This complete engine timing tool set is designed specifically for the high-performance Porsche 981 Cayman GT4 and 718 Cayman GT4, providing the exact tools required to accurately lock and align camshafts and the crankshaft during timing checks, timing chain replacement, cylinder-head servicing and VVT cam phaser adjustment.

Fits:

• Porsche Cayman GT4 3.8L 2015-16
• Porsche Cayman GT4 718 4.0L / GT4 RS 718 4.0L
• Porsche Cayman GT4 Clubsport
• Porsche Cayman GT4 RS Clubsport 2020-2024

With their motorsport-derived flat-six engines, the GT4 models demand absolute timing precision. Even minor timing deviation can affect power delivery, throttle response, VVT operation and overall engine health. This professional-grade tool kit ensures that engine timing is set correctly and consistently during every service or rebuild procedure.

Engineered to meet the accuracy standards required for Porsche GT engines, this tool set is an essential asset for workshops, engine builders and advanced enthusiasts working on GT4 power units.

What This Complete Timing Tool Set Does

This tool set is designed to:
Lock camshafts at the exact alignment position for timing chain or VVT servicing
Secure the crankshaft at true TDC, preventing rotation during repair
Synchronise camshafts and crankshaft for precise combustion timing
Enable accurate VVT cam phaser alignment on high-performance 4.0ltr and 3.8ltr GT4 engines
Maintain engine timing integrity during disassembly and reassembly
Assist with timing chain, tensioner and guide replacement
Support engine rebuilds with precise and repeatable alignment

The result is safe, accurate, professional-quality timing work on Porsche’s GT4 engines.

Why Timing Components Fail on GT4 Engines

The GT4’s naturally aspirated flat-six operates at high RPM and elevated temperatures, which increases timing system stress. Failure points may include:

• Timing chain stretch, particularly after track use
• Worn chain guides causing slack or cam deviation
• Tensioner fatigue leading to startup rattles
• VVT cam phaser wear, affecting valve timing accuracy
• Incorrect timing from previous repairs performed without proper tools
• Thermal cycling, causing expansion-related movement in timing components
• Oil contamination or varnish buildup affecting tensioner function

Common symptoms include misfires, power loss, VVT errors, uneven idle, hesitation and warning lights.

Why You Should Use a GT4-Specific Timing Tool Set

Using a precision-engineered timing set designed for Porsche GT engines ensures:

• Accurate and repeatable timing alignment
• Protection against piston-to-valve interference
• Proper VVT phaser calibration for GT4 performance
• Reliable timing chain installation
• Reduced risk of engine damage during rebuilds
• Professional results whether in a workshop or advanced home garage
• Confidence when servicing high-revving, high-value Porsche engines

GT engines require GT-grade tools—this set provides exactly that.
