1999 TC bearing failures , that's when the tensioner wear problem came to light . All '99 TCs had ball bearings for both cams in the support plate , the rear cam bearing failed . The fix for that was a roller bearing for the rear cam .
I've inspected tensioner shoes in later TCs with over 20k that showed minimal wear . The shoe material has been upgraded from the original stuff and seems to wear much better .
I wouldn't hesitate purchasing an early TC depending upon condition and price . Gotta see how it runs and rides , does it start cold with proper idles . The Magnetti Marelli EFI is a good system if set up properly .
