Saturn Ion replaced timing chain, maintenance going forward

Asked by Oct 09, 2016 at 02:42 AM about the 2004 Saturn ION 1

Question type: Maintenance & Repair

My sister's Saturn Ion just had the timing chain go at 96,000 miles. Was
surprised by this but researched and found out this is pretty common. The
place that installed the new chain has recommended flushing with a sludge
cleaner at each oil change as well as switching to full synthetic oil from now
on. Does this sound right?

If the mechanic found some sludge in the engine while doing the repair, one time would be fine. Regular oil changes are important, but using a cleaner at each oil change is excessive. No need to switch to full synth. unless she wants to go longer between oil changes. Cost more of course. But conventional oil is fine in the saturn.

Thanks for your input. That's what I thought but I have no experience with Saturn's or any other GM vehicles with this engine. I was shocked when she told me what the problem turned out to be. I thought it was great that it had a chain instead of a belt. Live and learn
