Closer than it appears.
After a decade on BMW M groups and forums, I've found the rod bearing dilemma to be excessively religious in nature.
I trust in science.
In this entry, I document my rod bearing service on my original S65B40 engine.
I link to fundamentals on bearings, echo the rational for my bearing & bolts selection from my previous V10 experience and cover the plethora of signature pictures of the original bearings.
Enjoy,
