Again to my point of warm up protocols. Frequent oil changes and so on.

Thank you for this valuable information. The improved locating tabs on LCI S65 engines gives me some added confidence.
This is one of the better videos I've seen on the subject. It shows 2011 LCI bearings as well as 2008 bearings removed from M3s. It also shows the 'dropping-the-sub-frame' method of changing.
