Many Porsche owners will experience failures with the IMS bearing in their vehicle, but it can be difficult to understand exactly what that means for you since it is a problem that is specific to Porsche vehicles. The term IMS stands for Intermediate Shaft Bearing. This part is an important to the proper function of your vehicle. The IMS bearing is located on the flywheel end of your car’s engine and is what supports the intermediate shaft.

The purpose of the IMS is to help drive the camshaft away from the crankshaft. The IMS bearing also helps increase the life span of the chain because the speed is reduced and allows for less wear. The intermediate shaft bearing system works through using pressure on the bearings that give oil to the motor.

Why Does the Intermediate Shaft Bearing Fail?

There are a number of factors that can contribute to the failure of the immediate shaft bearing in your vehicle and more often than not, such a failure is the result of many different issues. Each IMS bearing has a limited lifespan and depending on maintenance, driving conditions, and amount of driving your IMS bearing may wear down faster.

Another factor to the failure of your IMS bearing is a lack of oil lubrication to the bearing itself. Mixed with a high load, the intermediate shaft bearing will overheat, resulting in friction that will wear down the bearing and may even cause the bearing to crack.

How to Tell if the IMS Bearing is Failing

The most obvious sign of an issue with the IMS bearing will be a knocking sound from within the engine. The knocking sound will originate from the rear of the motor. This sound is not good and should be addressed immediately, as it can indicate a number of alarming problems with your vehicle.

Another issue you may experience is that when doing an oil change you may notice some metal particulates inside of the filter. If you notice any metal debris or hear any knocking sounds, it is important to take your vehicle to a trusted mechanic who will be able to diagnosis the issue properly.

Even though it may happen infrequently, if you have an intermediate shaft bearing failure, it could lead to timing issues in your engine. The contact from the valve to the piston requires specific timing, and if thrown off can result in an expensive repair. In that case you would need to entirely remove and disassemble your engine and replace the IMS bearing, as well as possibly rebuild or replace the entire motor. Again, this problem happens in rare cases, but it is an issue that should be considered when initially experiencing any IMS bearing problems. It is also why it is recommended to deal with intermediate shaft bearing failure as soon as you begin to notice malfunctions.

When dealing with an IMS bearing issue, depending on the model of your vehicle you may have to entirely remove the engine in order to be able to access the location. It is important to take preventative steps in order to prevent a failure of this system. If you have a failure of the system, it is not as simple as just changing the part because you may have other damage to the engine. This is costly and is why it is recommended to service your vehicle regularly.
