Over the weekend while I was changing my thermostat, I decided to take a look at my turbo.  I have a stock turbo in my 86 Ttype.  So I rotated the blades by hand which seemed a little too easy.  I also grabbed the end and was able to move it up and down and left to right.  I'm sure this thing needs new seals and bearings especially since there is a fair amount of oil passing into my plumbing and TB.  Would it be easier to just rebuild this?  What else could be wrong with this turbo?  I would hate to take this thing apart assming all I need to do is rebuild it and find out that it needs some major parts...which would push me in the direction of purchasing a new one.?
