2002 Nissan Maxima Timing Belt/chain

2002 Maxima does not use timing belt, thus breakage should be rare. Because it uses a timing chain, a failing chain would most likely show rough engine performance due to wear in the links, resulting in chain slop/stretch, and thus changed the engine timing from optimal setting. I don't know the valve configuration of Maxima engine, whether it is interference or non-interference. If it is the latter, there should not be engine damage.
