#3 bearing thrust for lunch.

Well sounds like you have a real delema. I hope its not ketching as the 318 in my truck is exibiting the same symthoms. The whole damper/pulley assy is moving in and out about 1/4" when I rev it up. Makes the belts squel all the time. I'm working on a different motor for it so I just keep driving it. It's my dayly driver. I will tear this motor down when I pull it and look for a reason but thats not going to be for a few months unless it goes BOOM.
