My new SL 350 (R230)

Hello together, After having driven around with a W124 station wagon at MT at the end of the 90s (then still as a student), I bought a 350SL today as a family father (44J old, 3 offspring and the better half). Admittedly, rather less for the family than for me and perhaps the elder (12J) – if he was good. The SL has the M112 with 245hp from March 2004. 1st hand, 50T km, PDC, multi-contour seat and the audio30 (grrr) and the usual rear disk sealing repair I have a question directly to you: On the engine (passenger side above the ignition coils – see picture) there is some oil. Where does this come from (if this is typical or known)? Urgent to be active there? Does this come from the seal right next to it? Would it be great if you could give me a direction here. Otherwise really awesome the sled (in particular coming from the Alhambra as a family carriage). And no, I am aware of no one. 500s tested so that I don’t even have the comparison at all. Look forward to discussions here and also one or the other repair on the car. Best regards Carsten
