Stripped spark plug threads in a 911 head usually means one of two things– a compromised repair or an engine drop to do it properly.
Until now.
STOMSKI RACING's new 911 Spark Plug Hole Repair Kit allows you to either accurately chase the threads of the damaged head, or if necessary, effectuate a complete fix by installing a Time-Sert (or Big-Sert). Our new digitally designed and CNC machined jig mounts over two of the valve cover studs, and when locked down with the included thumb screws, allows Time-Sert reamers, chasers, taps, and setters to be precisely aligned by way of the jig's guide tube and custom tap driver– all while the engine is still in the car.
Available in two different versions:
• SR130 for use with the standard M14x1.25 TimeSert Kit, and Inserts (TS4412E & TS44111) and;
• SR130BS for use with Big-Sert M14x1.25 oversized Insert Kit, and Inserts (TS5141E & TS51407).
We also have Time-Sert/Big-Sert 14x1.25 Kits and Inserts available for the complete package.

Sprocket alignment on the 911 engine requires an accurate and repeatable ability to measure the offset of the sprockets and lay shaft. Simply using a straight edge and vernier calipers requires at least three hands and rarely produces precise measurements. Now, with the SR008, measuring sprocket alignment on the 911 engine has never been simpler, more accurate, or more repeatable. A precisely fabricated block of 6061 aluminum secures an oversized Starrett straight edge (included) to enable easy and exact measurements. No more guessing or settling for "close enough."
Includes custom caliper base, as well as thumb screws for mounting on all 911 engines including the 964.

For engines where you do not have to use our "dead-stop" TDC Indicator (SR022/23), use our easy to use, highly accurate TDC Indicator With Travel Gauge to measure the exact position of the piston. Precisely manufactured from 6061 Aluminum and hard-coated for extra wear resistance, these indicators include ASME/ANSI certified travel gauges for proven accuracy. Not recommended for use on the hemispherical heads on air-cooled 911s.
Available for either 10mm, 12mm, or 14mm spark plug holes.

To ensure the utmost in timing precision, the true TDC of all engines should be checked to confirm the accuracy of the pulley TDC mark in relation to the real TDC. This tool screws into the spark plug hole and gives a mechanical indication of where the piston is in relation to the pulley/crankshaft. By rotating the crankshaft and touching/bumping the piston against the dead stop BTDC, and then rotating the engine in the opposite direction and touching/bumping the piston again against the dead stop ATDC, recording both measurements on a degree wheel, the pulley, or our DigiDix- SR095, you can calculate pure TDC.
Available for either 12mm or 14mm spark plug holes.

Installing O-rings on the through bolts for a 911 engine case often slices the rings on the threads of the bolt, leading to ripped seals at best, or a leaky engine at worst. Use this cap to protect the O-ring and to insure a factory quality seal. Precisely machined from quality brass.

Based on the factory P9511 tool, STOMSKI RACING's version of this tool incorporates a brass cap and a double-ended stainless steel sleeve to install the o-rings on the crankcase through-bolts of the 3.6 and later cases (but possibly can be used on some other 911 engines). By using the included brass cap to protect the delicate o-ring from getting cut on the threads of the bolt, you then use the "thin" end of the sleeve to slide the o-ring over the brass cap onto the shank of the through-bolt. Once the o-ring is clear of the threads, remove the SR024 brass cap and flip the SR024 stainless steel sleeve over and use the blunted end to securely and gently seat the o-ring in the recess on the 3.6 case.

The established method of setting valve lash with a feeler gauge often provides for a "close enough" result and rarely provides for accurate, consistent, and easy to obtain precision. STOMSKI RACING's new version of an old-standby takes the "feel" out of setting valves and provides absolute precision, speed, ease of use, and consistency. By conveniently mounting a travel indicator over the adjuster of the rocker arm, STOMSKI RACING's 911 Valve Lash Adjuster allows you to quickly and accurately set and confirm the actual valve lash without settling for "close enough" or wondering whether your feel is consistent while trying to contort a feeler gauge into the far reaches of the 911 engine.
The SR097 is precision machined from 6061 aluminum and anodized for years of service on all 911 engines including 964s and 993s. Also available are a range of dial indicators including metric, digital, and compact travel indicators for use in restricted areas (pictured).
PLEASE NOTE: this tool does not come with the gauge

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.
