ps2cho What I'd do is remove the MAF sensor and look. Even if you are completely DIY inept, you should be able to do this yourself. Watch this video, dont clean the MAF, just for procedure.

Once its off you should be able to see. My only guess is valve cover, crankcase vent system or its the cam covers that are just leaking downwards. There is no oil seepage from the MAF itself.

ALL the M272 crankcase vent valves leak. If it hasnt been done yet, its probably time. Just remove the bolts with a torx piece and swap out. Easy as that. Dont pay anyone.

2009 E-350 W211 - Engine M272 - Oil sipping at back of the engine

Hello all. I have 2009 E-350 W211. I has the M272 Engine it it. At the back of the Engine, there is small black looking holder, it seems like oil vapor return line that goes into it. The black holder seems to be sipping some oil. It is not leaking, but you can see some sip-page of oil. Below are the photos.

Can any one please kindly guide me to what is this small black plasticity looking container is and why I am seeing oil sip-page there.

Again my car is 2009 and has M272 engine in it.
