The timing chain cover has an oil leak.
There are two different 3.0 engines for your Sable: SOHC, or DOHC; single overhead cam, or dual. The timing cover is a big job on either, as there are a lot of parts that need to be removed in order to gain access to the cover. If you would like to have your leak inspected and repaired, consider YourMechanic - our mechanics provide diagnostics at your home or office.
