remember my sporadic overheating problems that culminated in engine noise I
assumed was the water pump?
removed water pump belt, still squealing, not the water pump
swapped in new tensioner pulley, still squealing, not the tensioner pulley
not exactly squealing actually: this is an intermittent chirping/chattering
at the rear of the engine when the engine is running, generally at lower rpms
definitely sounds like metal on metal - bearing noise
sounds loudest around the crank pulley
is there a bearing in there? main seal? crank bearing???!!!
any suggestions? I'm pretty well at the limits of my "expertise"
thanks very much
