Engine Timing Tool Kit – Precision Camshaft & Crank Alignment for Porsche M96 & M97 Engines

This Engine Timing Tool Kit provides the essential precision tools required to correctly check and set camshaft and crankshaft timing on a wide range of Porsche models, including the 911 (996 & 997.1), Boxster 986, and 987.1 Boxster / Cayman models using the M96 and M97 engines.

Accurate valve timing is vital for the performance, reliability and safety of these flat-six engines. Even slight misalignment can cause misfires, cam deviation faults, loss of power or—in the worst cases—serious mechanical damage. This professional-grade timing kit ensures perfect alignment during rebuilds, timing chain service, camshaft replacement or diagnostic inspection.

Supplied in a durable storage case, the kit includes equivalents to specialist tools typically referenced under engineering codes 9685, 9686, 9595 and 9595/1.

This makes it suitable for a wide range of mid-2000s water-cooled flat-six engines used across several Porsche platforms.

What an Engine Timing Tool Kit Does

A professional timing kit ensures precise and secure alignment of internal engine components by:

• Locking camshafts in the exact timing position
• Holding the crankshaft at top dead centre for correct reference
  
• Allowing accurate valve timing during assembly and inspection
  
• Supporting timing chain and tensioner setup
• Ensuring safe and repeatable timing for diagnostics and rebuilds
• Preventing rotational movement while critical components are serviced

This ensures optimal combustion, smooth running and long-term reliability.

Why Engine Timing Components Fail or Require Adjustment

The M96 and M97 engines are known for timing-related service demands. Common causes for requiring a timing tool kit include:

• Timing chain stretch leading to cam deviation
  
• Worn tensioners or chain guides
• Rebuild procedures requiring camshaft removal
• IMS-related service or bearing replacement
• Incorrect timing after previous repairs
• Top-end overhaul or valve-train replacement

Symptoms can include rough idle, hesitation, fault codes, loss of power or unusual noises.

Why You Should Use Your Timing Tool Kit

Using a precise, high-quality timing tool kit ensures:

• Accurate camshaft and crankshaft alignment
• Correct valve timing for optimal engine performance
• Prevention of piston-to-valve contact
• A faster, more reliable rebuild process
• Professional results consistent with engineering specifications
• Better diagnostic capability for timing-related faults

A worn or incomplete tool kit risks incorrect timing and potentially catastrophic engine damage.
