Porsche IMS Bearing Retrofit
Rennology Motor Sport is an LN Engineering Preferred Installer for the IMS Bearing Retrofit Kit. We have installed hundreds of bearings over the years and strongly recommend the LN Engineering kit as the best solution to the IMS Bearing Problems that all 1997-2008 Boxster, Cayman, and 911 engines can suffer.
There’s significant discussion on the subject of the IMS Bearing and its common failure. The bearing is similar to an axle bearing, in that it is a sealed unit housing steel balls and a permanent lubricant. The seals and the lubricant inside the IMS Bearing are intended to last for the life of your engine. However, as the IMS bearing ages, it has significant potential to deteriorate. The results of the failure lead to a costly engine rebuild or replacement.
Eventually, the IMS Bearing’s outer race begins to make contact with the IMS flange. This damages both the Intermediate Shaft and the flange itself. The result is the valve-train timing becomes compromised and components collide resulting in metal debris traveling throughout the engine. At this point, an engine rebuild or a replacement engine are the likely outcomes.
The Porsche M96 engine and its derivatives through 2008 have the potential failure of the ball-bearing found in the intermediate shaft. The intermediate shaft found in the M96 and later M97 engine was revised by Porsche three times. The earliest design was a dual-row ball-bearing used through model year 1999 and in some 2000 models. Later in 2000, a single row ball-bearing with a significantly reduced load capacity was used. In 2002, all engines switched to using this smaller, lower capacity bearing.
In 2006, the design was again revised to use a much larger single row bearing with the same load capacity of the early dual-row ball-bearings. However, in 2006 Porsche made its third revision of the intermediate shaft bearing by changing to a design that is not serviceable without engine dis-assembly. In all revisions, a sealed ball-bearing style was used, rather than allowing for engine oil located in the wet sump to lubricate and cool the ball-bearing.
Porsche IMS Bearing Retrofit
With exception of Turbo, GT2, or GT3 models, all 1997-2008 Boxster, Cayman, and 911 engines can suffer from IMS failures. Rennology Motor Sport Inc installs and supports the LN Engineering IMS Retrofit Pro Bearing to protect against IMS bearing failure. This is the only way to definitely protect and safeguard your Porsche Boxster, Cayman, and 911 models against an IMS bearing failure.
The Good News
With the expanded knowledge of the IMS problem most potential Porsche buyers are asking the right questions when they go to negotiate the price of a used Porsche that falls in the problematic years. Investing the money to address the problem not only provides you peace of mind in regard to not having a blown engine, but also guarantees a better asking price when you go to sell your Porsche.
