My C250 W204 2013 is leaking oil from the gasket area of the oil filter housing.
I am planning to tackle this soon and was wondering if anyone can give me some tips.
Can it be done by either removing the starter or the top air box?
Any suggestion?

Hi,
Mine is supercharged M271 and I did mine from the top, I don't think it would be possible to do from underneath.
Order new inlet manifold to head gaskets I think that theses are 4 o ring style and then the oil filter housing to block and housing to oil cooler shaped o rings.
Mine did 125,000km and the starter completely failed due oil had got to the brushes, if yours is anywhere near this milage I would highly recommend install new starter at the same time.
I did change the starter last month.
Your M271 setup looks different than mine but still I think I can access all the bolts from top if I remove the air box.
I checked already before asking, apparently there are not specific to this car.
I am capable of DIY this one, I have replaced starter, done the tranny fluid change, valve cover gasket etc but just wanted to be prepared before going in.
I will be doing the work this weekend.
I will ask again so someone can chime in.
Is it possible to do the work from the top just by removing the air filter housing or I have to remove the starter to get to all the oil filter housing bolts?

The WIS shows either removal of the starter (271.9 engine) or unscrew starter and place to one side (271.8 engine). It's just a couple of bolts so I would remove to make life easier. Please take pictures as this is next on my list of chasing down oil leaks (already completed the valve cover gasket and the turbo oil line).

Thanks, I just replaced the starter less than 2 months ago. It's very straight forward, I just did not want to deal with the starter again, lol.
Will take picture once I do it.
I am planning to change the entire housing instead just replacing the gasket., any thought?

I replaced the starter in June of last year and the alternator last month. As you said, the starter was simple but the alternator was a bit more of a pain.
I would be surprised if the housing is warped but then again over-torquing the oil filter cap over time might cause problems. My guess is that enthusiastic tightening of the cap coupled with age and hot/cold engine cycling causes the gasket to leak. But hey, it's all part of the Mercedes SLCS (Self-Lubricating Chassis System).
I've been facing this same oil filter housing leak on my 2012 C250 (120k miles) for the past year. I found this thread with another MB owner who completed the repair on the same M271 engine on his W212. He did it from the bottom by removing the starter and was able to access the five oil filter housing bolts: https://mbworld.org/forums/e-class-w...w212-m271.html
Further down the thread he links to a pdf with instructions on how he did the repair, it looks like he didn't even have to go in from the top.

I am not sure 2012 W212 and 2013 W204 the same steps to replace this filter.
I read about a one thing before I do anything to make sure I can remove the hose clamp for the coolant inlet hose. Any idea why this one is so difficult? Awkward location or need special tool?

It seems like tackling from just the bottom it's in an awkward spot, so the flexible hose clamp pliers are needed. With the inlet manifold out it looks like the clamp on the hose would be much more accessible, and standard clamp pliers could likely be used.

I attempted to replace the oil filter housing.
I had to remove the starter. First, I removed the air filter box but that did not give enough clearance to do the work, someone may be able to but I wasn't.
So, after removing the starter the 5 bolts are of the oil filter housing were accessible but I needed a flexible hose clamp plier to remove a hose going into the water pump. I put the starter back and called it a day.
It's very difficult to work under the car, I used a pair of ramp which don't give enough clearance to work using 2 hands.
I will take it to a shop and get it taken care of.

Sorry it didn't work out. I had to purchase flexible hose clamp pliers a couple of years ago to replace the coolant expansion tank on a Boxster. A bear of a job. It was still difficult with the pliers but would have been impossible without them. I hope your oil leaks are a thing of the past when the shop replaces the housing and gasket.

I did order one the flex pliers from Amazon and just received it, but don't foll like crawling under car again, lol.
I have been thinking, since I can remove starter in less than 20 min, why not try one more time since I have the clamp tool. I am planning to tackle the gasket once again.
Question to the ones who have done this, how difficult it is to remove the hose from the housing after loosening the clamp with this tool now, which prevented me from finishing the job last time. Do i need anything special tools? I know the space is very narrow.

The inside surface of coolant hoses often bond to the fitting. A small pick between the hose and the fitting to release the tension usually works well. You can also use channel locks to rotate the hose back and forward but you run the risk of damaging the outside of the hose with the jaws on the pliers.

How did these hose clamp pliers end up working? Were you able to get the hose clamp off with these once the starter was removed?

So, I need to replace the gasket for sure now asap, entire summer there was not a drop leaked from the oil filter housing but the very first cold day when the temp dropped below 39 degrees, I noticed a slump of fresh oil on the drive way. I just started the car and parked on the other side of the drive way to make room for my wife to take her car out, and there I noticed the oil. How can it leak so much in less than 3 minutes? In the warmer afternoon the same day only noticed few drops.
Has anyone done this job so you can share if the oil filter housing can be removed form the top? Any tips and video link would be appreciated.
Here's the pic of the housing location in my car. I found some references when I googled for info but the W204 comes up with different housing location.

I have the same model as you, and this project is still on my active list. Unfortunately, the camshaft adjuster replacement jumped to the top of the queue. Here are the steps from the WIS. From their description, it appears that you have to remove the intake manifold and the oil filter housing from the top side. I plan just to remove the starter first and see if it is possible to replace the gasket without the extra top side work.
@alynch I tried once, I removed the starter and it bolts were accessible but the hose clamp seemed very difficult to access and remove, so I put the started back and called it a day.
As you suggested, the intake manifold , the air filter and housing = intake manifold? I may try that. I don't want to remove the bolts and be stuck with the hose clamp, that would not be nice.
