You may be better off not disassembling the turbo. The rebuild kits give you new seals, but if you remove the shaft and turbine wheels, you'll need to have it rebalanced. Once you take it apart, your going to disturb the shaft, and chances are good, that the only thing keeping it oil tight at this point is the carbon build up in the ringlands. A small (very small) amount of shaft play is normal, as oil pressure keeps the shaft from contacting the bearing surface, just like the plain bearings on your crankshaft. I tried one of those rebuild kits on my first turbo, thats how I learned this. Try it first, if you have problems try contacting TurboCity ( you can google this to find their website) They can rebuild your center section, and it comes with a warrenty, or you can purchase a rebuilt center from them and exchange your core. Pay careful attention to the oil drain line, use at least a AN10 size line, braided stainless, or push lock.
