1996 Saturn SL1 Question: How long a timing chain will last before needs to be replace?

Some engines have inherent design problems , but generally a timing chain will last 150,000 miles or more if the engine oil is changed frequently. I have heard the Saturn engines give timing chain problems. About 6.5 hour job to replace on that engine.
