Re: Is my new GTP38R too loose?
They use Hydro-Dynamic bearings like Holset. Axial and radial play is OK. Just like stated, the pressurized oil causes the shaft to center. Most oil clearances between bearing/shaft surfaces are anywhere from 1-3 Thousandths. As long as the wheels are not hitting the housing, most likely the turbo is in spec. If you use a dial indicator, Garrett should be able to supply the service limits and you can verify if you are really worried.
