Sorry to disagree. I am 90+% sure what you have is a problem with these small tubes the MB referrs to as "oil bridges". There are relatively easy to replace and not expensive, I'd either do them all or at least the all of them on the bank which seems noisiest. Do a search here at the site and you'll see more info and how-to-do-it stuff. This has been relatively common on these 119 engines.
YES those E420's sure do "pull" don't they?! One of my favorites.
