Cam sprocket bolt tool for Porsche 993

stomski

STOMSKI RACING's version of the factory P9582 tool combines the basics of the factory tool and improves on it by adding an integral 19mm bushed socket that prevents slippage and rounding off of the cam bolt on the end of the 993 cam shafts. The cam bolt on the 993s requires a torque of 88 foot pounds. Tightening the bolt to this spec, or loosening it using a breaker bar and the factory long-armed cam tool requires dexterity, leverage, and serious luck that the deep socket does not slip off the head of the bolt, rounding it over, or busting knuckles in the process.

STOMSKI RACING's SR9582 securely holds an impact-quality socket in the center of a precision machined hardened steel socket, ensuring ease and accuracy in loosening the bolt, or setting the required torque. The bushing prevents the socket from being leveraged off the bolt head, keeping it squarely in place for the most accurate torque and security during installation and removal.

Diagram Ref No 24

Engine fasteners are subjected to continual heat cycles, vibration, and mechanical stress. Over time, original nuts can become corroded, suffer thread damage, or lose their ability to maintain the correct torque. This OE Match replacement restores the original specification and is ideal for engine rebuilds, repairs, and preventative maintenance.  

What This Product Does:
  • Secures the camshaft housing to the engine assembly.
  • Maintains the correct clamping force on the camshaft housing.
  • Helps ensure an effective seal between mating components.
  • Resists loosening caused by engine vibration.
  • Supports reliable engine assembly and operation.
  • Restores the original factory specification.
  • Replaces worn, damaged, or corroded original fasteners.

Symptoms Of Wear Or Failure:
  • Corroded or rusted fasteners.
  • Rounded or damaged socket head.
  • Stripped or damaged threads.
  • Nut failing to achieve the correct torque.
  • Signs of previous overtightening or stretching.
  • Loose camshaft housing fasteners.
  • Oil seepage around the camshaft housing due to reduced clamping force.
  • Missing hardware following engine repairs.
  • Visible wear or mechanical damage.
  • Fasteners showing signs of fatigue after repeated use.

Why Replacement Matters:

  • The camshaft housing relies on correctly torqued fasteners to maintain alignment and provide an even clamping load across the sealing surfaces. Worn, damaged, or corroded nuts can compromise this clamping force, potentially leading to oil leaks, reduced reliability, or costly engine damage.
  • Replacing ageing fasteners with OE Match components helps ensure the camshaft housing remains securely fastened and maintains the correct sealing pressure. Manufactured to OE-style specifications, this M8 socket head nut provides the correct fit, dependable performance, and factory-quality finish, making it an essential component during engine maintenance, repairs, or full restoration of your classic Porsche.

About Camshaft covers / Gaskets

Camshaft Covers & Gaskets – Engine Protection and Leak Prevention for Porsche Engines

Camshaft covers and gaskets play a vital role in sealing and protecting your Porsche’s engine. The camshaft cover (often called a rocker cover or valve cover) encloses the top of the engine, shielding internal components like the camshaft, valves, and timing chain from debris, oil loss, and contaminants. The gasket provides an airtight seal between the cover and cylinder head, preventing oil leaks and maintaining proper engine lubrication.

At Design911, we supply a wide range of genuine and high-quality camshaft covers and gaskets for numerous Porsche models such as 356, 924, 944, 928, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is engineered for a perfect fit and superior durability, ensuring long-lasting sealing and protection for high-performance Porsche engines.

What Do Camshaft Covers & Gaskets Do?

These components are essential for engine integrity and performance. Their functions include:

Sealing the camshaft area to prevent oil leaks and contamination. Protecting internal components from dust, dirt, and debris. Maintaining crankcase pressure balance for efficient engine operation. Reducing oil consumption and ensuring consistent lubrication.

Proper sealing is critical for preventing oil leaks that can affect engine performance or damage ignition components.

Why Do Camshaft Covers & Gaskets Fail?

Camshaft covers and gaskets are subjected to extreme heat, vibration, and pressure, which can cause material fatigue and degradation over time. Common causes of failure include:

  • Heat cycling causing gasket hardening and cracking.
  • Oil contamination breaking down gasket material.
  • Warped or corroded covers reducing sealing effectiveness.
  • Improper installation or overtightening of bolts.
  • Age-related wear and long service intervals.

Signs of failure include visible oil leaks, burning oil smell, engine misfires, or oil residue around the camshaft cover area.

Why Replace Camshaft Covers & Gaskets?

Replacing damaged or leaking camshaft covers and gaskets ensures proper sealing, protects internal components, and prevents oil loss. Neglecting these parts can lead to oil contamination, engine misfires, or even long-term engine damage.

Benefits of replacement include:

  • Eliminates oil leaks and residue buildup.
  • Prevents damage to ignition coils and spark plugs.
  • Improves engine performance and longevity.
  • Ensures clean, efficient lubrication with manufacturer-quality sealing.

All components available at Design911 are crafted from high-grade aluminium, composite, or reinforced rubber materials, ensuring superior sealing performance and heat resistance for long-term reliability.
