My Pontiac has about 158,000 miles on it, on the original timing chain. Should I get that replaced, or is a chain a real problem with breaking. The car starts and runs good, so it is not showing any signs of stretching.

Normally I'd say leave it alone. However, if this is a 3.1L code T motor they had a tendency to be fine and then either the chain would break or the cam gear would let go which caused a lot of these motors to get bent valves. You take your chances. I would rotate the motor by hand and feel how much slack is in the chain and base my decision on that. Good luck.

the computer compensates for stretching until the chain jumps a tooth...unless you are doing it yourself it is almost as cheap to replace engine with a newer one than replacing chain...my 97 gp the chain jumped tooth at 245k...repair cost was 735.00 low mile engine installed was 1300.00...i had newer engine installed...
