Daughter's 2001 SL2 has a serious problem -- engine runs but makes terrible
& loud banging noise. A mechanic listened briefly and said it sounds like she threw a rod. Took the valve cover off & everything looks good & clean, plenty of oil. Just 90,000 miles on the car. She went to the dealership (w/o the car) and a salesperson told her that with Saturns there could be another cause for this that a mechanic not experienced with Saturns might not think of...but she didn't catch what it was he said, other than it might not be as serious as needing a rebuilt engine. Any idea what he might have been talking about? |

If I had to guess (which strangers on a message forum probably won't do well
since we haven't seen/heard the car...), I'd say either the timing chain is on its way out, or a rod bearing is toast. The most common cause of either is neglecting to check the oil and keep it at the proper level, or change it at the proper interval. I had a rod bearing fail prematurely and this is what it sounded like: http://www.evilplastic.com/sounds/knock.wav You can see what the guts of the motor looked like which caused this noise in the projects section of my website.
