Customer Question

I just bought a 2007 Pete with a c15 twin turbo and the turbos have play. They took the high side apart and the fan is broke on the inner part of the fan. The engine runs good and has good power on the low side and has no miss. Has low power on the high side. What could have caused this?

Hi. Thanks for asking your question and requesting me! I will try and help you out.
Can you describe the break on the turbo fan? Is there just one fin broken off?
Customer: replied 2 years ago.
All the fins are damaged

Thanks for the information.
So all the fins leading edges are damaged? Not the sides?
Customer: replied 2 years ago.
The side
Expert:  Cat Man replied 2 years ago.
I see. Thanks for the information.
If there is side damged this can only be caused by bearing wear in the turbo. You are very lucky to catch it now. The reason is this type of problem leads to a catastrophic turbo failure. When the wear gets worse, the contact will become greater and then the turbo wheel or turbo shaft will fail.
Please reply back if you need more help or have more questions. I am happy to assist.
