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?
