well after the teardown, motor still in car hahaha, the crank is not scored and the rod looks good. I guess i cought it just in time. I DID not beat on or rev the motor when it had the knock, so i am just going to replace the rod bearings for now. I would do a full build but i need a car!! Right now I have my supra torn apart so i can drive that. I got lucky this time.
