Changed my oil a few months ago. At the time, I couldn't find a fleece filter locally so I used a paper one from the local auto parts store.

In the meantime, I ordered a few proper fleece filters online.

Recently started noticing oil on the floor of my garage. Opened the hood and it looked like oil had dripped down from where the oil filter assembly is attached to the engine. So, I changed the filter and the 4 o-rings with the new fleece filter set from Mann.

A few days later and I'm still seeing oil on the floor of my garage. Anyone experience something like this before ? It still looks to me like oil is coming down from where the oil filter is located.

Since you changed the o-rings, my guess would be that you have all kinds of oil that has collected at the bottom of the plastic underbody.

Get under there, remove it and clean it up.

Then there's always the possibility that the composite filter cap is cracked.

If there doesn't appear to be any "new" oil seeping from the cap area, then it's just the oil that has collected at the bottom.

Let me know!

could you have over-filled the oil reservoir? Remember, even if you add 8.5 quarts, you may not have drained 8.5 quarts and thus over-filled. Check the dipstick.

I hope that's the issue and will take it down and clean this weekend.

Eich

Pretty sure I got 8.5 quarts out when I drained it. But no dipstick on this car. Oil level is checked with car off, ignition "on" through the driver information center. And it checks out OK although I don't know if it could report overfill or not.

Probably a long shot but I managed to slide the large o ring past the groove to the very top of the filter cannister. It does not belong there. A cartoon print is included with Mann filters to show the proper location. If you had done this, you would get a lot more than oil puddling on the garage floor. The engine lost 2 quarts of oil in about 100 miles. Still, it might be worth checking.

This has happened to me earlier this year. Somehow I did not tighten the plastic filter cap enough and that caused the oil to leak out. Tighten the cap the clean the under body plastic cover.

Eich

Yep - I paid particular attention to where that large o-ring goes and I'm certain I put it in the correct place. But thanks for the suggestion.

Eich

I didn't think that you had to tighten that cap very tight since there are rubber o-rings in there. I don't have the proper MB tool to remove and tighten the cap but I also didn't think it had to be much more than hand-tight. The plastic rim around the cap is definitely contacting the engine and the o-rings are down below that.

Is there a torque spec for it if you do have the correct tool and use a torque wrench?

I have the tool that snaps onto a socket wrench but prior to that I hand tightened and had no leaks. You may need to clean the threads and grove for the main o-ring to ensure it's seating and sealing properly. One other thought, are you sure you're not get some leakage from your oil filler cap..........it also has a rubber seal that can loose its pressure to prevent seepage. I bought a replacement cap last year to ensure no seepage on my engine. The rubber seal is permanently attached so you have to buy a replacement cap that's inexpensive. I learned from an expert Volvo mechanic I use for Volvo V70 that the rubber seal should be replaced peridically to prevent leakage on the engine..........likewise the metal gasket on the oil drain plug should be replaced during each oil change. I don't know if my Benz has a metal gasket on the oil drain plug since I've never changed the oil myself...........does anyone know?

About a couple of years ago, I was in either Autozone or Pep Boys looking for some tool to tighten the cap because the hand tighten method is just not enough, and adjustable oil filter wrench I used was scratching the plastic cap badly. I saw an adjustable belt-type wrench and figured that should do the trick. The set came with two, a large one and a smaller one. I keep the smaller one in the kitchen to open tight jars and the large one in the garage for the cap or any other purposes. They work great and very easy to use!

I bought the oil filter socket (it's a metal cap that fits over the oil filter cap) from Ebay for something like $10.

Thanks for all the replies. After installing the new Mann filter and o-rings, I haven't seen any evidence of new leaks around the oil filter cap and have never seen any evidence of leaking around the filler cap. Had a little more oil on the floor for a few days but that did appear to be residual oil on the plastic under pans.

I do think I need to tighten the cap a little more though to prevent future leaks. Does this appear to be the correct wrench?

The spec for my 05 E320 CDI filter is 27nm and I use that part plus a torque wrench. Also, I add my oil to the filter housing while the filter is out. It seems to go in the engine faster. You have to be a little careful because the housing is at an angle and it is easy to add too much at a time and it will drip over the edge. I solved that problem by making sure I had a spotlight in my garage aimed at the filter housing and I just take my time. No spills anymore.

..... and the torque spec for E320 gas engines is 25Nm.

Not sure that's the right one. I bought from a site that states it fits the W211.

Thanks! I just purchased that one, which is a 74mm
