I went to ln engineering and see the IMS bearing is for up to 2005.
I was under the impression the issue went until 2013? |

M96 engines used the dual row bearing from 97-2000. The single row from 2001-2005. The M97 engine brought with it an IMS Bearing that was 26% larger and can't be retrofitted with the processes I invented due to the bearing being larger than the crankcase port used to remove it. The M97 used this bearing through 2008. In 2009 the factory gave us the 9a1 engine, with no IMSB, and a host of other issues. 2009 is NOT a magic year, and the future will prove what we've been seeing for 5 years working with the 9a1 engines, some that have failed at only 4,165 miles. The GT3 and Turbo engines utilized the Mezger design IMS/ Layshaft through 2013 when they were also replaced with the 2 chain engine, missing a layshaft for the first time. Attached thumbnail(s)
