Hello. Just completed an oil change a few days ago and noticed that the plastic engine protector had some oil on it. After looking at the bottom of the engine closer, I noticed oil coming from an unknown part below the alternator and from the 1 to 2 o'clock position of the oil pan.

I haven't had the time to get the car on the jacks and FORGOT to write the part number down of the part below the alternator. All I know is that it was a Bosch part.

Was curious if anyone know off hand what that part was or if this is a common problem with the C280. It's a 1997 with 86000 and has the "new" design head gasket that was done around 63000.

Thanks so much!
