I am wondering if anyone can clarify or give a spec about how much up and down (radial?) play is within acceptable limits on a Garrett t3 turbo.
I have no back and forth (axial?) free play on my turbo, but about 1/64th up and down. My understanding is that this may be normal as the shaft rides on a cushion of oil which takes up this slack while the engine is running.
Is this correct?
This question pertains to my wife's daily driver (82 300D), so I would like to avoid down time to rebuild if possible.
Many thanks,
Ray

Correct. The in/out play is what you want to have none of.

The limits are 0.022" (0.56mm) side/side and 0.008" (0.20mm) in/out. Too much play would result in the blades rubbing the housing. The oil pressure automatically takes up the clearance and centers the shaft.

Many thanks for the info.
Now on to the oil cooler lines...
