Product Information
Exhaust bolt repair kit for Boxster / 996 / 997 Carrera & Cayman Gen1 1997- 2009 (Not GT3, GT2 or TT engines)

stomski

With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.

Now also includes our SR065D drill guide.

About Cylinder Head / Camshaft Carrier

Precision Cylinder Head & Camshaft Covers – Engine Protection and Performance for Porsche Models

The cylinder head and camshaft covers play a vital role in protecting key engine components such as the valvetrain, camshafts, and cylinder head from dirt, debris, and oil contamination. Beyond protection, they ensure proper oil sealing and ventilation — maintaining consistent lubrication and pressure balance within the engine.

At Design911, we offer a wide selection of precision-engineered cylinder head and camshaft covers for both classic and modern Porsche engines. Crafted from high-grade aluminium, magnesium, and composite materials, these covers provide a perfect fit and long-lasting reliability while maintaining the clean, professional look expected from Porsche’s performance heritage.

Whether you’re restoring an air-cooled 911 or servicing a high-output 992, our manufacturer-quality components ensure leak-free operation and exceptional durability.

What Do Cylinder Head and Camshaft Covers Do?

These components serve as the protective shell for your engine’s valvetrain and upper oil channels. They keep contaminants out, manage internal pressure, and help maintain consistent lubrication.

Core Functions:

  • Seal the upper engine area, preventing oil leaks and contamination.
  • Protect the camshafts and valve train from debris and moisture.
  • Regulate crankcase ventilation, supporting optimal engine breathing.
  • Maintain correct oil flow for cooling and lubrication efficiency.

They are essential not only for reliability but also for maintaining the visual and mechanical integrity of your Porsche’s engine bay.

Why Do Cylinder Head / Camshaft Covers Fail?

Over time, heat, pressure, and oil exposure can degrade materials, seals, and gaskets. These issues can lead to leaks, poor ventilation, and even oil starvation in extreme cases.

Common Causes of Failure Include:

  • Cracked or warped covers from repeated heat cycles.
  • Degraded seals or gaskets, causing oil leaks.
  • Loose or fatigued fasteners, leading to uneven sealing pressure.
  • Blocked breather passages, increasing internal pressure.
  • Corrosion or contamination in older engines.

Replacing worn covers and seals restores oil control, prevents leaks, and preserves long-term engine health.

Why Replace with Precision-Engineered Covers?

Upgrading or replacing your covers ensures your Porsche engine operates as intended — leak-free, properly ventilated, and visually clean.

Key Benefits:

  • Restores sealing performance and eliminates oil leaks.
  • Protects vital valvetrain components from dirt and debris.
  • Maintains proper crankcase pressure and oil control.
  • Crafted from premium materials for superior heat and corrosion resistance.
  • Perfect fitment and finish, ensuring long-term reliability.
  • Compatible with a wide range of Porsche models, from classics to modern GT cars.

Precision covers also contribute to the engine’s aesthetic, maintaining the refined look Porsche owners expect.

Highlights:

  • High-strength cylinder head and camshaft covers for Porsche engines.
  • Precision-machined sealing surfaces for long-term oil-tight performance.
  • Manufacturer-quality materials – aluminium, magnesium, and composite options.
  • Improved oil control and internal ventilation. Ideal for engine rebuilds, upgrades, or restorations.
  • Compatible with air-cooled and water-cooled Porsche models.
