Idler Bearings - Gone again after 1100 miles?!

I took my new to me 2002 stock Turbo in for a Tech inspection prior to a track day coming up next week. As soon as the tech drove it into the garage, we both noticed a loud ticking/grinding sort of noise coming from the engine. I imagined a timing chain or valve train catastrophe about to happen. After diagnosis by two mechanics with stethoscopes, the verdict was the idler pulley bearing(s) are about to go. It does sort of sound like a bad bearing, and seemed to get worse just running for some minutes on the lift. It clearly is coming from the center of the engine (left to right) and the back side. It comes apart Monday.

I did get full records with the car, and 1.8 years / 1100 miles ago, all 3 idlers were replace. Is this something to expect - seems like an awfully short time to be replacing the idler(s) again. What might be causing the problem here??

Could simply be a bad idler; it happens, we have seen bad ones right out of the box.
