The vast majority of failures are related to the rotating assembly e.g. Main and rod bearing failures.

Has there ever been a single case of main bearing failure? Not that I have seen.
What is "properly set", factory values?
There is no "solution" less custom crank undersizing AFAIK. It's also still debatable if BMW bearing clearances have caused any lack of reliability so hence I refer to this a a "solution".
