You can definitely tell from spinning the shaft. Friend of mine had a big apexi bb turbo on his rx7 and that sucker spun forever even just by hand.

I was told that you can look into the turbo where the oil return is and shine a light in there. You can see the bearing shining on a turbonetics ball bearing turbo.

most turbos spin while idling. people have told me in the past that their turbo was stationary during idle, and i can't help but think that is an indication of a problem.

LIKE TOP NOTCH SAID.. you flip the turbo to the oil drain. if you see a silver ball looking circle you will see it shine about 1/8 inch round. otherwise all you see is a shaft and metal casting
