Buying a Used Porsche 911? Lookout for This Hidden Horror

And if you are in the market for a used Porsche 911, there is one hidden horror you need to lookout for before making a purchase. While the Porsche 911 is an iconic sports car known for its performance and luxury, there is a common issue that can be costly to repair if not addressed properly. This issue is known as the IMS (Intermediate Shaft) bearing failure.

The IMS bearing is a small but crucial component in the engine of a Porsche 911. It supports the intermediate shaft that drives the camshaft, helping to regulate the timing of the engine valves. However, over time, the IMS bearing can wear out or fail, leading to catastrophic engine failure if not replaced.

The cost of repairing an IMS bearing failure can be significant, often costing thousands of dollars. In some cases, the engine may even need to be rebuilt or replaced entirely, resulting in a hefty bill for the owner. This is why it is essential to check for signs of IMS bearing failure before buying a used Porsche 911.

One common indicator of IMS bearing failure is a loud knocking or ticking noise coming from the engine. This noise can be a sign that the IMS bearing is worn out and in need of replacement. Additionally, if you notice any oil leaks around the IMS bearing or excessive vibrations while driving, these can also be signs of impending failure.

To avoid the headache and expense of dealing with an IMS bearing failure, it is crucial to have a pre-purchase inspection done by a reputable Porsche mechanic. They can perform a thorough inspection of the car, including checking the condition of the IMS bearing and looking for any other potential issues. It is also recommended to ask the seller for any maintenance records or receipts related to the IMS bearing replacement, as this can help determine if the issue has already been addressed.

In some cases, it may be possible to proactively replace the IMS bearing as a preventative measure. This can be a costly but worthwhile investment, as it can potentially save you from the even greater expense of an IMS bearing failure down the line. Additionally, some aftermarket companies offer upgraded IMS bearing kits that are more durable and less prone to failure, providing added peace of mind for Porsche 911 owners.

Overall, while the Porsche 911 is a desirable and high-performance sports car, it is essential to be aware of the potential issue of IMS bearing failure when buying a used model. By being vigilant and proactive in checking for signs of IMS bearing issues and having a thorough inspection done by a qualified mechanic, you can help ensure a smoother and more enjoyable ownership experience.
