IMS Bearing Issue in Porsche

Is It Real? Causes, Failures, and Solutions


The intermediate shaft bearing (IMS) is a recurring topic among Porsche vehicles owners, particularly for certain models manufactured between 1997 and 2008. While it has sparked concerns and frequent debates within the Porsche community, it is essential to address the subject with accurate information and an objective perspective.

 

IMS Failure in Porsche:

What It Is and the Risks


Is it a real issue? Not exactly. Like any mechanical component in the engine, it can wear out or fail. The IMS bearing is a part that helps synchronise the camshafts with the crankshaft. In some cases, it may wear prematurely, leading to severe engine failures. However, the failure rate varies depending on the type of vehicle, its usage, and its maintenance history.

 

How to Prevent IMS Failure in a Porsche:

Solutions and Recommended Maintenance


Preventive maintenance is key. For owners seeking peace of mind, several options are available:

 

IMS Inspection: This involves assessing the condition of the bearing and its lubrication to detect any signs of wear. It is advisable to carry out this inspection when servicing the vehicle’s clutch system. This way, the required disassembly and reassembly work is optimised.


IMS Replacement: If wear is detected, the best solution may be the same as for any other vehicle component replacing it with a reinforced version (not an original manufacturer part).


Proper IMS Lubrication: To maximise the lifespan of the IMS, it is crucial to follow the manufacturer’s recommendations and use Mobil-1 5W40 or 0W40 oil. In some cases, lubrication can be improved by installing an additional lubrication system (not an original manufacturer part). This system provides better oil supply to the IMS, reducing premature wear and helping to prevent failures.

 

Should You Inspect the IMS in Your Porsche?

Preventive Maintenance Is Always the Best Option


Every case is unique. Not all Porsche vehicles with an IMS bearing are at risk of failure. However, if you have concerns about your vehicle’s condition, it is best to have it inspected by specialist technicians. At Sauri Classics, our team of professionals has the experience and tools necessary to provide the best solutions and proper maintenance for your model, always following the manufacturer’s specifications.
