I checked the play in the turbine shaft and there is NO play up and down and NO play side to side. Actually, it seems a bit tighter than when I first got the turbo.
After I put all of the turbo gear back on the new motor, I noticed that when I first started the motor up, there was a small (and the only one)oil leak that came from the rear turbine housing. It was between the dump pipe of the back and the gasket.
I am thinking that the rear turbo seal has gone.
What do you guys think?
