Take the inlet hose off the inlet side of the turbo and see if the blades are hitting the housing.Grab the end of the shaft and feel for excess loseness.Look under turbo and where you see the buypass valve ,give it a good soaking of PB blaster or whatever they sell for heat riser valves.Chack for old vaccumm holes at the pressure control valve to the turbo.Chack all exhuast fittings? Your turbo can run under pressure and not be hitting ,but when pressure is off its just spinning freely."HOWWWWWING" My 87/9000t I think is just starting to get a hint of this/160.000miles
