Probable cause
Fatigue failure of the No. 4 inner main bearing cap screw and connecting rod bolts, which resulted in a total loss of engine power. Contributing to the failure were the low material strength of the inner main bearing cap screw and the increased loads on the screw due to wear in the No. 1 fuel injector.
