Common 911 Issues: Preventative Maintenance is Key

Every Porsche 911 is a masterpiece, but like any precision machine, it has its vulnerabilities. We’ve worked with countless 911s, and we understand the most common issues that can arise. Here’s a closer look at some of the challenges faced by water-cooled 911 owners, and how we can address them:

• IMS Bearing Failure: IMS bearing failure is a well-known issue, particularly in earlier 996 and 997 models. If left unaddressed, this issue can lead to catastrophic engine failure, leaving you with a costly repair bill. Fortunately, we can help prevent this disaster with thorough inspections and the option for a retrofitted bearing solution. Learn more about IMS bearing retrofitting here.

• Bore Scoring: Bore scoring, which is often associated with excessive oil consumption, engine misfires, or unusual sounds, can have a major impact on engine performance and longevity. If not dealt with promptly, bore scoring can lead to irreversible damage. Our team specializes in diagnosing and addressing bore scoring, whether that means engine repair, rebuild, or a full replacement.

• Cooling System Leaks and Water Pump Failures: Cooling system issues are a concern across all water-cooled 911 models, and if neglected, they can cause overheating and engine failure.

• Water Pump Failures: A malfunctioning water pump can result in overheating, putting your engine at risk of severe damage. If you notice abnormal engine temperatures or leaks, it's crucial to address this issue immediately to avoid costly repairs.

• Turbo Coolant Pipe Leaks: On 911 Turbo models, especially the 996 and 997 generations, the aluminum coolant pipes can become prone to leaks as they age. Over time, the adhesive securing these pipes can break down, causing coolant loss. If ignored, this can lead to engine damage. We offer a lasting solution by securely pinning or welding the pipes, preventing future leaks and preserving engine health.

• Suspension and Strut Wear: Suspension components are essential for maintaining handling and stability, especially in a high-performance vehicle like the 911. Worn-out struts, shocks, or bushings can cause poor handling, a rough ride, and an overall less enjoyable driving experience. Delaying these repairs can result in further damage to your suspension system, ultimately impacting your vehicle’s performance and safety. Let us restore your 911’s handling to factory standards or beyond.

• Ignition Coil Failure: A flashing check engine light or poor engine performance—especially after driving through rain or a car wash—could indicate ignition coil failure. This issue can lead to misfires, poor acceleration, and decreased fuel efficiency. Our team can replace your failing coils with upgraded parts, ensuring a smooth-running engine and avoiding the need for more costly repairs down the road.

• Sloppy Shifters: A shifter that doesn’t respond as crisply as it should is more than just an annoyance—it can make driving your 911 less enjoyable. Worn-out shift components can lead to imprecise gear changes and reduced driving satisfaction. We can install high-performance Numeric Racing shifters and cables to enhance that precise, connected feeling you love.

• Outdated Stereos: Your 911 deserves a modern stereo system that complements its performance. If your factory stereo feels outdated, we offer the Porsche Classic Communication Management (PCCM) system, which integrates modern features such as Apple Carplay and Android Auto while maintaining the sleek look of your Porsche’s interior. This upgrade enhances both your driving experience and the value of your vehicle.
