Stomski Racing SR024 Through bolt o-ring installer with sleeve for Porsche 911



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.

Through bolt o-ring installer for Porsche 911



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.

TDC indicators for Porsche 911



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.

Sold separately.

TDC indicator with travel gauge for Porsche 911



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.

Sold separately.

Sprocket registration pin puller for Porsche 911



This unique tool allows you to easily pull the cam timing sprocket registration pin. No more yanking on the factory tool, hurting your fingers, or pulling the sprocket off the end of the cam shaft. Use this precisely machined slide hammer to delicately pull the pin.

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.

Anodized Aluminum.

Heat exchanger tester for Porsche 996 / 997



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.

Leak-down / compression adapter for Porsche 911



You no longer need to fight or snake a flexible rubber hose blindly through the valve cover and into the cylinder head to hook up a compression or leak down gauge on the 911 engines (or other engines with remote spark plugs). Simply insert this unique tool into the spark plug hole of the cylinder head and attach your gauge. Precisely machined from high quality stainless steel or hard-coated aluminum.

Available in two sizes based on spark plug thread/diameter.

Sold separately.
