Porsche IMS Failure and Repair Experts

There is much discussion and worry in the Porsche community about the potential failure of Intermediate Shaft Bearings (IMS) in 9X6 9X7 models. Because of this, there has been a surge of aftermarket products designed to address Porsche IMS failure, and this issue creates a lot of confusion among consumers. There are special oils, warning systems, modified bearings, and retrofits. There is one product marketed as a “solution” but it is only available for 2005 and earlier models unless you commit to a total engine teardown. This “solution” for IMS failure eliminates the oil pressure bypass circuit, and complicates regular servicing by forcing you to use an aftermarket oil filter that may not be readily available at your preferred garage.

With one exception, all of these so-called solutions treat the symptom (bearing/engine failure) as opposed to attacking the root cause: lack of lubrication.

When an IMS failure occurs, debris contaminates the entire engine. A complete engine disassembly is then required to replace the intermediate shaft. In worst-case scenarios, the cam timing can also be thrown off, casing value to piston contact, and lead to a catastrophic failure. Replacement of the engine then becomes your only option. Over the years, R.S. Motorwerks has been closely following various solutions. Most only treat the symptom, but we treat the root cause.
