Sorry to post so many questions so quickly but that's what happens when you finally sign up to a good forum heh

Either way the s600 has an oil leak from engine that's not VERY serious but a few drops...

Impossible to tell where its coming from due to the cover on the bottom (sump guard?) where the oil collects and drips from it. As soon as I get the car on some ramps, I'll take that off and be able to pinpoint the problem a bit better, but was just wondering is there a rather prone spot to leaking? Any common areas and if so how hard are the seals to replace?

P.S. It's definitely oil and not any other fluid!
