At rest, the chain is somewhat loose. Tightens up when engine is running. The issue is not the timing chain. It's with the plastic chain guides.
While it's tough to attribute the main reason why the guides break (statistically it is very very very small), some ways to prevent it is fresh oil changes and stop using ASS.
