Porsche IMS Bearing

Symptoms Associated with Your Porsche IMS Bearing Failure

by admin October 13, 2024

Porsche models are popular for their mind-blowing engine performance. This is due to state-of-the-art features and years of designs that make Porsche engines function to their maximum abilities. However, that enormous horsepower you love and expect can wax and wane if various engine problems, common to Porsche models, crop up.

An IMS bearing failure is one example of the common problems associated with Porsche models. This puts your model at risk of engine failure. So, we have provided this guide to help Porsche owners understand the functions of the IMS bearing, the signs of failure, and the best course of action to prevent the risk of engine failure.

The IMS Bearing—Functions and Causes of Failure

The IMS bearing is a component in your Porsche that aids and supports the InterMediate Shaft (IMS). The Intermediate shaft plays an essential role in engine function by driving the camshaft off the crankshaft. However, since the camshaft needs to be driven at half the speed of the crankshaft for effective engine function, the intermediate shaft also aids the speed reduction that makes this possible.

Also, the IMS reduces the risk of wear caused by extreme stress on the camshaft drive chains during rotation. In essence, the IMS bearing helps the intermediate shaft perform its duty and protect the engine and its components.

Like all functional components in vehicles, the IMS bearing could fail due to the following reasons:

  • Wear and Damage: Wear and damage to the intermediate shaft bearing is one of the major causes of failure. For instance, the bearing has seals that help to keep internal grease and lubrication in. If these seals wear out, there will be excessive friction which could damage the bearing and other engine components.
  • Poor maintenance: The inability to properly maintain the intermediate shaft and its bearing is also a major cause of failure. Maintenance actions like frequent oil checks and changes, lubrication, and cleaning the engine area help to keep parts like the IMS bearing in good shape.
  • Design or Installation Flaws: Another common cause of IMS bearing failure in most Porsches is a design flaw from the manufacturers. If you recently changed the IMS bearing in your car and you start experiencing signs of failure, it could be that the bearing was not installed properly or was poorly designed. A design issue could be that the bearing material is not durable enough to handle the intermediate shaft’s load.

3 Symptoms to Help You Identify IMS Bearing Problems in Your Porsche

If you notice any of the following signs in your Porsche model, it could be due to a failing IMS bearing:

  1. Poor Engine Performance: One of the common signs of a failing IMS bearing is poor engine performance. Since this bearing supports the intermediate shaft, it means that when it fails to provide this support, the shaft may begin to develop some issues that could affect the camshaft and eventually, the engine’s performance.
  2. Loud Noises: Another sign that could indicate a faulty IMS bearing is loud, unusual noises from the engine bay. If you hear rattling noises or you notice excessive vibrations coming from the engine area, then it could be due to a faulty IMS bearing. These noises come when the bearing does not support the intermediate shaft, causing unusual movements.
  3. Oil Contaminations: Another sign to indicate that your Porsche’s IMS bearing could be failing is when the oil or oil filter is contaminated by metal shavings. The intermediate shaft bearing is made of metallic materials; So, when the bearing is faulty and begins to degrade, its metallic parts break into the engine’s oil.  You may only notice this with regular oil checks and changes.
