Warn Out Turbo? How to tell?
On my '88 TII, how can I tell that the turbo is warn out? The car dosent seem to be boosting at all, and I wanna know how exactly to tell if its the turbo thats warn? Will it have play in it? Will it make noise? How can I rule everything else out and know its the turbo? Thanks guys any info would be great!

well, even a bad turbo will make boost...listen for an unusually noisy turbo on throttle, does it's burn oil a lot...is there oil visible in the TID or by the BOV? if you remove the turbo itself is there a lot of play and wiggle in the shaft and do the blades look clean and straight? doesn't sound like an actual turbo problem to me...if your car isn't boosting that seems like a problem with possibly a clogged exhaust/cat or vacuum issues.
