You may even find that it is your vacuum pump to chain cover joint that is leaking. I had two reputable MB Indies say my leak was in fact the front main based on oil spray & drip location. Drips on the street like your photos. Not a lot of oil lost. I figured I had bigger fish to fry for the $ like a new vacuum pump.

So I put a new V.Pump in and...go figure...the oil leak stopped. Now I can park in the driveway! Check it out. I've heard of several others finding the same result.

PS the car now has 330k on the original front main seal.
