not sure of the excact cause of this, but some problems the owner had.... green stuff air filter, not mantained with signs of dirt in the intake, banks 6 gun and no egt gauge, and nasty, NASTY engine oil, #1 and #6 both had ring failures, #1 broke top and 2nd rings and most of them were gone, #6 broke the top ring and some how, pieces of it made it up on top of the piston and beat the heck out of the piston and head, #2,3,4,5 all look perfect....
