Using the "Clevite Engine Distress Guide" and the Clevite bearing guide: http://catalog.mahleclevite.com/bearing/ determine the cause of the failure of this bearing.
Looking at the picture and using the Clevite Distress Guide, my best guess for cause of failure would be bearing overload due to a number of things. Bumping up power of the engine would cause this overload as it is turning so fast the oil does not have proper time to fill the void and it creates air bubbles which burst and create the cavitation. Another cause would be to poor engine oil quality or the an entirely wrong oil application.
I think it could be distorted misaligned bearing. here is a link to my findings: http://catalog.mahleclevite.com/bearing/

ReplyDeleteto me when i looked at the Clevite Distress guide,i belive it is either misaligned main bores or a bent crank shaft.
ReplyDeleteof course the way the chipping on the bearing i would say in conjuction with my own thoughts is the bubbling and cavitation Jared is saying above.
I think this is hot short caused by poor oil quality or contamination.
