I have seen some early Corolla's that make this noise, while it sounds like a bearing, it is not.
Possible torque convertor, torque convertor bolts to flexplate, PS pump etc.
I have a 91 that has made this noise for the last 60K.
I changed engines, transmissions, oil pump, waterpump, stem seals, alternator, camshaft shims, CV axles, and noise is still there.
I don't worry about it.
Change oil every 3-5K and trans fluid every 24K. Flush and drain cooling system every 2 years.
