I am always curious about swapping timing belts out at that interval. I'm sure some engines have design issues but 100k seems silly to me. I have two Toyota 4.7Ls, one with 180K and the other over 400K...both on the original timing belts. Junk yard motors to drop in if they go are cheap enough IMHO to take the risk.

To the mechanics on here... how often do you actually see snapped or jumped belts on any motors? Maybe I'm just lucky but I wouldn't bother with the belt.
