very very good info in this thread!!

Thank you Husker for a thorough explanation

What many do not discuss with the 05.5 and up M97 engines? The bearing is MUCH MUCH bigger than the M96 bearings (I mean diameter bigger) which means it turns at a lower rpm than the M96 bearing (it's already turning half of crankshaft speed) + it has more ball bearings!!

I haven't seen a failure of this larger M97 bearing (yet) and I have had 8-10 of them come through the shop (engines) and 15-20 987/Cayman customers.
