Engines are classified as interference or non-interference depending on whether or not damage will be done if the timing system (belt, chain, etc) should fail. Toyota, at least up to a point, only used belts (which will snap, eventually) on non-interference engines. In that case, if the belt snaps, no harm is done. On interference engines they only used chains, which essentially never break. I used to think all major manufacturers followed this rule... but lately found out it's not true. So now I have to find out about Mazda.
