Reason for LT6 engine failures ?

"During the development of the LT6, the engine team found hot spots in the main bearings that it attributed to cavitation near redline when the oil thinned out at high temperatures.
To combat that, the Z06 has a number of heat exchangers up front that keep oil temps below 200 degrees."
