Straight Talk about the IMS Bearing in the M-96 and M-97 Engine

Those 3 letters stand for something big – Intermediate Shaft (IMS). There has been much talk and information about it on the internet, some of it actually true, most just stories by people who have had a bad experience. Here are the nuts and bolts of it.

Porsche is no stranger to the IMS. Porsche has been using an IMS for along time. The 547 Carrera engine had one, in fact every 911 ever built has one. In the early engines, the IMS is known as a “layshaft” and does not present issues, even though it had the exact same job as the current IMS in regard to driving the camshafts. The problem is not the IMS but the IMSB (Intermediate Shaft Bearing) in the M96 and M97 engines. 

Your Check Engine Light and What it Really Means

It is back on again! Should I have my car towed in? Is my engine bad?

But what does that little light actually mean? And unlike the Mayan prediction of the end of the world, your problem may be very minor – or it just may indicate a larger, more obscure problem.

On-Board Diagnostics System

Use of the CEL began with the introduction of the On-Board Diagnostics II system (OBD) starting in 1996. This system is a government mandated vehicle component that automatically checks and tests various vehicle emissions control items.
