I have a turbo 400 with an aluminum drum, 300m input shaft in a stock case. I have roughly 200 miles since having this thing built. At first when running it sounded like a noisy convertor or a small clunk on revolutions. The last time I started it it had a screeching/ screaming noise coming from the pump area getting louder with rpm to move. I pulled it out and pulled it apart. Found metallic brass looking in the oil and noticed my stator tube bushing are shot. What would cause this? Thanks for all of the help. Gonna attempt to fix this on my own.
