yes, actually what I ended up doing is removing the external belts, one at a time and ran the engine. When I ran out of belts and it was still screaming I knew where I needed to go, although I initially assumed it was the water pump, which I already had 'in stock'. After I removed the timing belt tensioner pulley, and spun it in my hand, I realized by the screeching that I had found the source of the screaming. The idler pulley bearing just feels really 'rough', so what the heck, might as well replace it too. Ordered the parts today. THX....Rob
