Tips to Identify Porsche IMS Bearing Failure

Stephane Grabina • October 15, 2023

Porsche IMS (InterMediate Shaft) bearing failure is a concern that looms large for Porsche owners. This seemingly unassuming component plays a pivotal role in the engine’s performance and durability. In this article, we’ll dive deep into the topic, discussing what exactly the IMS bearing is, the significant risks associated with its failure, the invaluable benefits of proactive maintenance, and comprehensive guidance on identifying, mitigating, and rectifying IMS bearing problems.

What does the IMS bearing do?

The IMS bearing is a small but mission-critical component residing within the heart of a Porsche engine. It serves as the linchpin connecting the engine’s crankshaft to the camshaft, facilitating their harmonious synchronization. This synchronization is pivotal as it governs the timing of the engine’s valves. In simpler terms, the IMS bearing ensures the smooth operation of your Porsche’s engine.

The Down Sides of an IMS Bearing Failure

The consequences of IMS bearing failure can be catastrophic. When this modest yet indispensable component falters, it can lead to the intermediate shaft breaking or shifting, potentially causing severe damage to the engine. The worst-case scenario? Total engine failure. This not only translates to exorbitant repair costs but can also result in the need for a complete engine replacement. In essence, IMS bearing failure poses substantial financial and operational risks that no Porsche owner should overlook.

Address the Issue Sooner than Too Late

The wisdom of addressing IMS bearing concerns promptly cannot be overstated. There are several compelling benefits to proactive maintenance:

  • Financial Savings: Early detection and resolution of IMS bearing issues can save you from the staggering financial burden of engine repairs or replacement.
  • Preventing Stranded Moments: Swift action ensures you won’t find yourself stranded on the side of the road due to sudden engine failure, an experience that can be both inconvenient and costly.
  • Optimal Performance and Longevity: Maintaining a healthy IMS bearing is synonymous with an engine that operates at its peak, delivering optimal performance and an extended lifespan.

How to Identify IMS Bearing Issues

Now that we appreciate the gravity of IMS bearing health, let’s delve into the practical aspect of spotting potential problems:

  • Unusual Engine Noises: Pay close attention to your Porsche’s engine sounds. Rattling, grinding, or knocking noises emanating from the engine bay could be indicative of IMS bearing wear or damage.
  • Oil Leaks: IMS bearing problems often manifest as oil leaks near the rear of the engine. Regularly inspect your garage floor or driveway for telltale oil spots.
  • Vibrations: If you sense increased engine vibrations, particularly at higher RPMs, this might signify IMS bearing trouble.
  • Fluctuating Oil Pressure: Keep a vigilant eye on your oil pressure gauge. A fluctuating or consistently low oil pressure reading could signal IMS bearing issues.
  • Metal Shavings in Oil Filter: During an oil change, inspect the oil filter for any traces of metal shavings. The presence of such shavings is a glaring sign of IMS bearing wear.

Mitigating IMS Bearing Problems

If you suspect IMS bearing trouble or wish to prevent it, here are the steps you can take:

  • Regular Inspections: Schedule periodic inspections with a certified Porsche technician. These inspections are essential for monitoring the condition of your IMS bearing.
  • IMS Bearing Upgrade: Consider opting for an upgraded IMS bearing solution, which can significantly diminish the risk of failure compared to the standard factory-installed bearing.
  • Proactive Maintenance: Adhere diligently to your Porsche manufacturer’s recommended maintenance schedule. This ensures comprehensive upkeep of your engine, including the IMS bearing.
