I've read a bit on the web, and I'd like someone to confirm for me
regarding my 98 Cherokee with 4L I6 Engine (105,000 miles):

1) The timing chain does not need to be replaced like timing belts do -
it should last as long as the engine.
2) If the timing chain should break, the engine is "non-interference"
so I don't have to worry about major damage like bent valves, etc.
Is this correct?

Thanks,
Mike
