Stomski Racing SR124 Engine case splitter for Porsche 911



No more hammering, chiseling, swearing, heating, prying or praying to get an 911 engine case apart. STOMSKI RACING'S SR124 ELEGANTLY and GENTLY separates the engine case halves and not only shortens the process of engine tear-down, but it also protects what doubtlessly is an expensive asset- the engine case itself. The rare #s matching early 911S sand-cast aluminum case, or the impossible to find 911 GT3 RSR case, or the early magnesium case that seems so fragile, all can NOW be protected from the threat of the block of wood and lead hammer, or the torch, or the pry-bar and chisel.
SR124 includes a CNC precision machined aluminum platform that you bolt to four head studs (ideally over #2 or #5) using the included thumbscrews. An over-sized drive-screw (stainless steel) is then threaded through the platform to mate with a high-load bearing in our specially designed rod cap that presses against the wrist pin of #2 or #5 connecting rod that is at bottom-dead-center. As you slowly use a wrench or ratchet to tighten the drive-screw, the torque of the SR124 splitter is evenly distributed through the entire crankshaft, pressing against ALL 8 main bearings. Once the slack is taken up, only GENTLE effort on the drive screw is required to split even the most belligerent of cases.
The SR124 platform is designed to work on all Mezger 911s (2.0 through 997) and includes Delrin inserts/sleeves that protect the head studs from scratches or dings.

A magnetic sump oil drain plug is a type of oil drain plug that contains a small magnet designed to attract and capture metallic particles that may be present in your engine's oil. While this type of drain plug is not exclusive to Porsche and can be used in various vehicles, it can provide several benefits, including:

Improved Engine Longevity: The magnet in the drain plug helps to capture tiny metal particles, such as iron, steel, or aluminum, that may circulate in the engine oil. Removing these particles can reduce wear and tear on engine components, potentially extending the engine's lifespan.

Enhanced Engine Performance: By reducing the presence of contaminants in the oil, a magnetic drain plug can help maintain the oil's lubricating properties, which is crucial for smooth engine operation. Clean oil can also contribute to improved fuel efficiency.

Early Detection of Problems: As the magnetic drain plug collects metallic debris, it can serve as an early warning system. By inspecting the drain plug during oil changes, you can get an idea of the engine's condition and detect any unusual wear or damage before it becomes a major issue.

Reduced Maintenance Costs: Regularly inspecting and cleaning a magnetic drain plug can prevent larger issues from developing over time. Addressing potential problems early can save you money on more extensive repairs down the road.

Peace of Mind: Knowing that you are taking steps to protect your engine from premature wear and tear can give you peace of mind as a vehicle owner. It's a relatively inexpensive and simple modification that can provide added assurance.

Easy Installation: Magnetic drain plugs are typically straightforward to install. They often replace the existing drain plug and require no special tools or modifications.

While magnetic drain plugs can offer these benefits, it's essential to remember that they are not a substitute for regular oil changes and proper maintenance. Regular oil changes with the appropriate oil and filter are still crucial for the health and longevity of your engine. Additionally, magnetic drain plugs may not capture all types of contaminants, so they should be seen as a supplementary measure rather than a comprehensive solution.

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.

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.
