[s-cars] Turbo question

[Tom Green]

Ivan,

Is there any noticeable play with oil pressure on the center  
bearing?   ;-)
That's when it counts.  It is difficult to check sideplay with the  
turbo spooled
up though.  Was there much oil in the Michelin Man hose ? The hoses  
and I/C
are  better indicators of condition before it leaks copious amounts  
of oil directly
past the turbine seal to the exhaust telling everyone your turbo is  
shot.
And, yes the shaft will have sideplay but if it doesn't come back,  
that's trouble.
