Why Camshaft Timing Systems Fail on Porsche MA1/MAB Engines

Modern Porsche engines rely on advanced VVT and multi-stage timing systems, which can fail due to:

• Timing chain stretch from age, heat and high RPM
  
• VVT (cam phaser) wear, affecting cam timing accuracy
  
• Tensioner degradation, causing rattle and timing deviation
  
• Improper timing after previous repairs without correct tools
  
• Oil contamination affecting chain lubrication and VVT function
  
• Thermal stress, leading to timing component movement

Symptoms include camshaft correlation errors, reduced performance, misfires, rough idle, power dips, or check-engine lights.

Why You Should Replace or Use a Precision Camshaft Timing Tool Kit

Using this dedicated Porsche timing tool kit ensures:

• Exact camshaft and crankshaft alignment
• Safe VVT adjuster servicing
• Correct chain tension and timing setup
• Protection from piston-to-valve contact
• Professional rebuild quality even for home workshops
  
• Reduced chance of timing errors and costly engine failure

For MA1/MAB engines, accurate tools are absolutely essential.

Crankcase head stud driver for Porsche All 911 964 993 996 / 997 GT3 & Turbo Models 1965-On



Double-nutting a head stud to install it into the engine case not only takes time, but can be stressful for the threads, and can lead to variations in stud depth (unless you are extra careful when removing the double nuts). Protect your hardware investment and speed installation by using STOMSKI RACING's Head Stud Driver.

Made from black oxide finished hardened steel, this uniquely designed tool threads onto the head stud but will not clamp on to the threads, making installation faster, gentler, and more accurate.

Exhaust bolt repair kit for Porsche DFI Engines on 911/997/991/ Boxster & Cayman (9A1) 2009-Onwards



Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR069, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Also includes our SR065D drill guide.

With the tight tolerances of the M96/M97 engine platform, accurate wrist pin alignment is essential. A misaligned or improperly fitted gudgeon clip can cause catastrophic engine failure, including piston damage, cylinder scoring, or wrist-pin walk. This tool set ensures safe, controlled and professional-grade installation every time.

The kit includes an alignment tool, a pin driver, and an extension, providing everything required for correct gudgeon clip positioning during engine rebuilds.

What This Wrist Pin Fitting Tool Does

This specialist tool kit allows you to:

• Precisely align the piston and wrist pin before installation
  
• Insert the wrist pin smoothly and accurately using the dedicated pin driver
  
• Seat gudgeon clips securely without distortion or damage
  
• Reduce the risk of clip misalignment that can cause engine damage
  
• Ensure correct piston-to-rod positioning during assembly
  
• Work efficiently in confined spaces with the included extension tool

This complete set is essential for professional engine rebuilders and experienced enthusiasts.

Kit Contents
1× Wrist Pin Alignment Tool – Ensures perfect piston/rod orientation
1× Pin Driver – Applies controlled force to install wrist pins
1× Extension – Provides reach for difficult-to-access bores and bank positions

Engineered for accuracy, durability and repeatable performance.

Why Wrist Pin & Gudgeon Clip Installation Fails

Incorrect installation can lead to:

• Clip deformation due to poor tools or improper force
  
• Incorrect seating, allowing the pin to drift
  
• Cylinder scoring if a clip dislodges while running
  
• Piston damage from misaligned pins
  
• Stress fractures in circlips due to over-compression
  
• Assembly errors caused by limited access in boxer engines

These issues can result in full engine failure, making proper tools essential.

Why You Should Replace or Use a Precision Wrist Pin Installation Tool

Using a specialist wrist pin fitting tool ensures:

• Accurate and safe gudgeon clip installation
• Protection from catastrophic wrist pin walk
• Professional-grade rebuild results
• Reduced risk of damage during assembly
• Consistent, repeatable clip seating
• Correct wrist pin/piston/rod alignment
• Confidence when rebuilding M96/M97 engines

This tool set eliminates guesswork and ensures clean, precise engine assembly.

Oil pressure relief plug extractor Porsche 911 / 964 / 993 / 996 / 997

Tolerance between the pressure relief plug and its galley are very close, and the slightest bit of gunk, corrosion, or bur will cause the plug to freeze up in the oil passage. A magnet is rarely powerful enough to overcome the seized plug, and leaving it in place is never an option.
Using STOMSKI RACING's Oil Pressure Relief Plug Extractor makes the task of removing the stuck plug a breeze, and allows you to ensure clean oil passages, and a properly operating bypass system.

The collet-based tool slides easily into the open end of the seized plug and a simple turn or two of the internal socket head cap screw expands the tool, grasping the plug to ensure easy removal.
