No, it wasn't installed incorrectly from the factory.
What happens at high mileage is the steal seal gets oil coking on it from mileage, and poor oil, and that causes it not to seal correctly anymore. The high RPM forces more oil to the seal, and it leaks. But that and the board members of a DSM forum have nothing to do with the design of the turbo.
SS autochrome and XSpower are Chinese copies of a Garret turbo.
Are they as good as garret? I don't know the answer to that.
I have seen multiple SS autochrome turbots installed correctly, and none of them have failed.
**”This is what I am telling you guys.”**
I have seen them installed on multiple Hondas, a TT Corvette, BMWs, my corolla, and my Lexus and none of them have failed.
Now if you'd like to post what they say in other forums, and hear what the inventory level of turbos is in Holland, then this is the place to be.
