I'm new to the forum and have owned my 2006 short/tall sprinter for a few months now. While on a short trip a few weeks ago I noticed some oil seepage coming from this moulded plastic interuption in what appears to me to be part of the turbo intake plumbing as there are large diameter flex hoses connected to either side. Could anyone tell me if this needs immediate attention? Could this moulded plastic part suffer a similar failure to the turbo resinator? It doesn't appear to be a loose hose clamp, I've checked them already. I'm not very familiar with the sprinter motor so any help would be appreciated.
