Problem Description and Possible Solution
Excessive timing chain noise, a rattling or ticking, on higher mileage cars may lead to timing chain failure, which can cause engine damage. There are upgraded chain tension guides with a steel backing to improve durability and a modified repair procedure no longer requires the removal of the cylinder head to replace the timing chain. Maintaining proper engine oil level and frequent oil changes are important to ensure the long-term durability of this engine.

At just over 100k miles either the tensioner and or guide gave out causing the timing chain to fail. The engine, which is of the interference type, was trashed as a result.
loose rattling timing chain has resulted in timing jumping as in no start, weak exhaust pulses as the intake valves are slightly open during compression stroke rather than intake and exhaust valves both being closed at tdc.
Timing chain noise, had my "great" mechanic replace it and now my vehicle runs like a "top"! Using a high grade synthetic motor oil for the entire life of my engine, helped tremendously.
