Premature timing belt failure on Subaru Loyale

Premature timing belt failure is not uncommon. The recommended service interval is 60K, but belt failures before that mileage have been noted. This 1.8L engine is considered "free-wheeling", therefore the chances of valve damage if the timing belt fails is minimal.
