Timing Chain

[Heath Vogt]

Sorry if this is a "check the archieves" question, but
I have checked.  My question is:  When does the timing
chain need to be replaced?  I have a '98 Sentra SE,
and I can't find anywhere in the manual that says
anything about timing chain replacement intervals.
Haven't been able to find it on Sentra.net or
searching the archieves.  If it's an easy search on
the archieves, tell me what to put in and I'll go that
route. TIA.
