[s-cars] funny noise after tbelt

[Randy Reimer]

About 2 weeks ago I had the t-belt, t-stat, water pump etc done.  Now that it's warm enough to drive with the windows down, I can hear an odd noise up front.

The audi manufacturers belt tensioner was not replaced but the bearing was switched out as per Bob Pastore's part number.  Car runs great but now makes an odd ratcheting noise.  Is constant, never goes away and making me very nervous.  Is it possible that the bearing when inserted was misaligned?   If the tensioner bearing were to fail, what happens?  Any BTDT's
