Hey I just gave my turbo a 5000 mile inspection and I noticed a few things that are concerning me that I thought I would share and see what you all thought.
First off, I was wondering that with a slight "pinch" in the SBR's rubber oil return line burt anything. What I mean is that it is nice and round @ top then about middle way it squeexy very slightly flatter then after the middle comes back to its full roundness.
Second, I checked for any signs of shaftplay....First I checked for any in & out movement, there is NONE. Then I checked for up and down, there is a VERY SLIGHT up and down movement, however when I pull up on it or down on it the turbine wheel still spins freely in the housing without the fins hitting the housing itself, Is this NORMAL wear on the turbo and when the inner housing fills with oil and the oil pressure builds, will this SLIGHT up and down movement dissappear as the oil travels through the bearings?
Lastly, when I received the turbo @ my residence, I noticed as you are looking into the cold side of the turbo, there is a ruff sliver of the casting inside the turbo housing right before the turbine fins and wheel. It is on the inside of the peice of the turbo which you slide the intake over, except for the fact that the ruff peice of casting is on the inside. I do not think this hurts a thing, however i wanted to bring it up.
