Porsche is well-known for producing high-performance sports cars. Their reputation sets them apart from other manufacturers. However, the IMS bearing is one of the most common problems in Porsche vehicles. This little-known component has caused misery for thousands of Porsche drivers who demand the maximum performance from their vehicles.
If you are a Porsche owner who is not already familiar with the IMS bearing, you should learn about it, because it may become a problem you will have to deal with later in your vehicle’s life.
The IMS bearing is merely a small component of the IMS system as a whole. IMS is an acronym for InterMediate Shaft. The IMS is a geared shaft that runs the length of the engine. Its purpose is to collect the crankshaft’s rotation and use that momentum to drive the camshafts. This is the type of mechanism used in Porsche’s flat-six engines. Ball bearings, also known as IMS bearings, support the shaft.
Causes of IMS Bearing Failure
The high failure rate of IMS bearings can be attributed to two factors.
- First, the bearings themselves are made of flimsy material that does not appear to be able to endure even moderate wear and tear, let alone the internal heat generated by the engine. Because Porsches are made to be pushed to their limits on occasion, even more strain is placed on these already fragile bearings.
- Lack of lubrication is the second most common cause of IMS bearing failure. This can also cause the bearings to deteriorate prematurely. In any case, the wear and tear on the bearings will contaminate the engine oil, hastening the engine’s demise.
Even though the IMS bearings are a minor component of a larger system, their failure can result in damage to other elements of the engine, necessitating costly and time-consuming repairs. The intermediate shaft must keep precise timing with the crankshaft, which can be thrown off by a broken bearing. This could result in smashed pistons and damaged valves, causing significant engine damage.
In the worst-case scenario, an IMS bearing failure can necessitate a total engine rebuild. You do not need to be told as a Porsche owner that a complete engine rebuild on your car will necessitate draining your bank account and handing it over to the repair shop. Fortunately, you may take precautions to ensure that this tragic situation does not occur with your prized Porsche.
Dealing With IMS Bearing Failure
There are a few additional strategies to cope with IMS failure besides keeping up with scheduled maintenance and monitoring for plastic or metal particles in your engine oil.
- You can avoid the problem entirely by replacing the bearing before it fails. Bearings on a Porsche produced between 1997 and 2005 are easily accessible, making proactive replacement much easier.
- You can also choose to change your oil and filter more frequently to keep track of whether or not debris is present.
- Speaking with an expert will help you identify the best course of action. If you bring your vehicle in for regular inspections and have a trusted technician, they will be able to work with you to evaluate which choice is best for your vehicle in the long run. Getting a professional opinion is essential because several elements decide whether you need to replace the complete IMS bearing.
