1999 Saab 9-5 Question: timing chain noise and low oil pressure light comes on at idle.
Answer #1Bret Bodas February 16, 2011, 00:45Master
Check the oil level first, then have the oil pressure checked and if it's low then have the low oil pressure issue fixed. Hopefully after that the timing chain noise will go away. Avoid driving it in this condition, you will only do more damage.
