IMS "Intermediate Shaft Bearing"
The purpose of the intermediate shaft is to drive the camshafts indirectly off the crankshaft. By using an intermediate shaft, the speed of the chains are reduced, which is better for chain life. This basic design was used throughout the entire lifespan of the aircooled six-cylinder Metzger engine used through 1998. The inclusion of an intermediate shaft which drives the camshafts indirectly off the crankshaft has been a mainstay of the horizontally-opposed flat 6 engine utilized by Porsche.
One thing is for sure. Once you have experienced an IMS bearing failure, there is no turning back. A complete engine dis-assembly is required to replace the intermediate shaft and in most cases, complete rebuild or engine replacement is your only option.
"So, its essential to perform replacement at the early stages of wear"
