what is a slight crack though,, and does it matter where it is,
i have a ct9a infront of me with one you can see going to the wheel, also have a ct9b where you have to look into the turbo, (direction of flow) to see the crack,
My turbo has a crack running from the wastagate to the turbine wheel I was concerned about it but it has not got ANY worse and it does not effect boost in the slightest, in terms of control or pressure.
