If you have owned a Porsche car model just lately, you must have heard of IMS bearings. If you happen to be confused about what you have read about such parts for your luxury car, it pays to get to know them better. On this page, you will learn more about what these bearings are and all other things you essentially need to know about them – from the problems they may cause in case they fail to the better solution to the problem.
What are IMS Bearings?
The IMS in the entire term IMS bearing stands for Intermediate Shaft Bearing. This makes this type of bearing a supporting part to that of the intermediate shaft. The intermediate shaft allows reduction of the chain speeds which will be better for the chain life. In the case of the Porsche, these bearings have been common to those car models from the brand that utilizes a flat-6 engine under the hood. These are seen in the various car models including the GT2, GT3, and Turbo among others and other newer models from the car maker.
Which Among Porsche Models Commonly Encounter IMS Bearing Failure?
The list will include 986 and 987 Boxster Models as well as 987 Cayman models with engine numbers of up to 61504715. It is also a common failure in all 996 models except Turbo and GT models. Problems may also occur if you own a 3.6-liter 997 car model with engine numbers of up to 6950745.
What are the Common Reasons for IMS Failure?
One of the reasons for common bearing failure is the process called spalling which results from normal causes like when the bearing reached its age and is in need of replacement. In the case of the IMS, spalling results from the lack of lubrication made to the IMS bearing. High load on the IMS bearing can also result to spalling. Overheating may also cook metals found in the bearing thus resulting to friction. All these can cause the IMS bearing to fail prematurely.
What Can be the Worst Case Scenario?
Valve to piston contact, for one, is a problem especially because the cam timing can be thrown off due to the failure of IMS bearings to do their job. This can compromise the effectiveness of the engine and can be taken as a sign that it will need replacement. Always remember that when you have encountered failure with your IMS bearing, then you have to disassemble the engine and replace the intermediate shaft. In almost all cases, you will need to either completely rebuild or replace the engine.
How Can the Common Problem Be Fixed?
Replacing the IMS bearing is just a proactive approach when this part fails. It is more important, however, to prevent this from happening. Taking steps to detect any problem at an early stage will minimize cost attributed to engine failure.
