Thanks for the reply. I checked the receipt and no mention of seal replacement. Yes, the oil is leaking on the driver's side near the wheel. It was running down from above and dripping off of the oil pan, but it was dark so I couldn't really trace where it was leaking from.

Based on your info, it's probably the crank seal or valve cover. I'll check for obvious leaks, and give the garage a call. They are pretty reasonable, so hopefully they'll swallow the cost on this.

I'll keep you posted. Thanks again.
