Mahle bearing failure

A couple of pics from my own engine which hadn´t even been started, just turned over for assembly.
Bearing crush was 0.008-0.010" instead of recommended 0.006". All eight rod bearings looked the same.

I've seen this on a build where they had a Source crank. It turned out the fillet radius on the journal was too big & the bearing showed it. To fix our situation, we chamfered the edge of the bearing.
