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.

Some M96/M97 engines are experiencing oil-to-coolant intermixing. While there are potentially several sources of intermixing, faulty engine mounted oil-to-coolant heat exchangers are a major source. Now, with STOMSKI RACING's M96 Heat Exchanger Tester, you can confirm if your exchanger is faulty and needs replacing, or whether the source of the contamination is elsewhere. This high-quality tool is CNC machined from 6061 aluminum, anodized for years of service, and comes complete with all gauges, seals and hardware.

Specialist Tools for Accurate, Efficient & High-Quality Porsche Engine Rebuilds
Engine rebuilds require precise measurements, correct assembly procedures and the right equipment to ensure every component fits and functions exactly as intended. Specialist tools are essential when working on Porsche engines due to their unique engineering, tight tolerances and model-specific service procedures. These tools enable technicians and enthusiasts to dismantle, inspect, rebuild and calibrate engines with professional accuracy—reducing the risk of damage, misalignment or incorrect installation.
Whether performing a full engine restoration, carrying out timing work, inspecting internal components or installing performance parts, using the correct specialist tools guarantees a reliable, long-lasting and high-quality rebuild.
What Specialist Engine Rebuild Tools Do
High-quality specialist tools ensure precision and safety
throughout the rebuild process. They are designed to:
- Accurately
measure critical tolerances, including bore, deck height, ring gap and
valve clearances
- Correctly
install and remove components such as crankshafts, pistons, liners and
bearings
- Support
timing procedures, including camshaft alignment and intermediate shaft
setup
- Prevent
damage to delicate components during disassembly and assembly
- Improve
rebuild efficiency with purpose-built fixtures and holding tools
- Ensure
even torque application, promoting proper sealing and component
longevity
- Assist in diagnostic tasks such as leak-down testing or compression verification
Specialist tools are essential for achieving a professional-grade engine build with reliable and repeatable results.
Why Workshop Tools Wear or Fail
Even well-engineered tools degrade over time due to heavy
use, improper handling or exposure to harsh environments. Common causes of
failure include:
- Metal
fatigue from repeated loading
- Worn
or stripped threads on pullers, press tools or torque tools
- Corrosion
from moisture or chemical exposure
- Heat
damage from working near exhaust or cylinder heads
- Loss
of calibration, particularly with measuring or torque-sensitive tools
- Damaged
contact points from misuse or excessive force
- Contamination from debris or workshop dirt
A failing tool can cause inaccurate measurements, unsafe working conditions or even costly engine damage.
Why Specialist Tools Should Be Replaced or Upgraded
Replacing worn tools or upgrading to precision-engineered
alternatives provides clear benefits:
- Improved
measurement accuracy for critical engine dimensions
- More
reliable component installation, reducing the risk of misalignment
- Safer
workshop practices, preventing injury or engine damage
- Consistent
torque and calibration, essential for sealing and bearing load
- Enhanced
efficiency, saving time during complex rebuild procedures
- Better
compatibility with modern engines and performance upgrades
- Higher quality rebuild outcomes, improving engine reliability and longevity
Using proper tools is an investment in the quality of the rebuild and the health of the engine.
