(HELP Needed) Engine leakage
Hi guys,
Today I've been replacing the Air Mass Flow Meter and noticed a considerable amount of oil leakage that's been covered by dust just right on top (see photo) and beneath the engine. This you can only see when engine plastic cover with air filters is removed.
Is this something I should worry about and If yes - what parts and labor hours am I looking at? How long can I drive with this (If it's a problem). Thanks in advance.
P.S. So many disappointments with my baby these days

I have some oil too around the covers and manifold too, but not as much as you do. Look at the rubber seal around the valve covers (the big silver cover the coil packs sit on, you have two, one on either side of the block). Are they worn or bits of it missing?
First thing I would do is check my oil level. Make sure its fine. Second, if the rubber seals are worn, then you probably want to have them replaced. SHOULDN'T cost too much, but being that its a Mercedes, dealers are probably going to rip you off.
In general, its doesn't look to be a serious problem. Clean the all that oil off and see if it comes back in a few days of driving. Check your oil level frequently.

I want to clean up my engine, because it has a lot of salt deposits on it and some dirt and oil here and there.

I recomend that you use 3m aerosol brake cleaner or comparable and compressed air (if available). With eng. off, spray cleaner directly on soiled areas, wire harnesses, injectors, coils will wash away dirt/grease (and sometimes paint so b careful) with no problem...and it dries quickly w/little residue.

Did you go with the IK16s? Where did you get them? I'm ready to buy them, its just I cannot justify paying near $200 for a set of 16.

from the looks of it, it isnt a continuing leak as its covered in dust,
its probably from when someone changed the oil and whilst refiliing spilt some in the wrong place,
use some engine gunk to clean it off,
dont wash with water, there are alot of electricals in a w220 engine.
once clean give it a check te if is leaking, then take it from there, but teh fact its covered in dust, i assume no leak at present!

Replacing valve cover gaskets.
Hello everybody I'm pretty new to this forum. Here is my tech questions.
Having the same situation with my engine I've ordered two of the valve cover gaskets and the original Mercedes-Benz Sealant
Since my rubber seal looks badly worn out I want to fix that asap. Say I unscrew everything, remove the valve cover itself and tear off the old rubber gasket.
Now. Do I have to replace the valve cover gaskets alone or do I still have to apply sealant on them when putting valve cover back on? If yes, then where exactly should sealant be applied?
Thanks in advance to all knowledgeble techs here.

Could you please be more specific about "torque it correctly". What do you mean by that?

The valve cover's breather cover is leaking oil. There are alot of Mercedes that do this. Over time both sides will eventually leak. There isn't any special way of doing it, just make sure its not oily when you put it back on with the new sealant and it will work just fine for a good long while. One thing you might be careful of is to not apply too much new sealant to the breather cover when you put it back on. Just a small bead of it all the way around the cover and the bolt holes will do just fine. I prefer to take the valve covers off first though so that I can thoroughly clean off the valve covers and especially in the breather area, plus it doesn't hurt to have a new valve cover gasket on there. Finally, you might stick a small drill bit or something into the breather hole to expand it just a tad. Over time those holes will close up due to the residue being sucked through the valve covers.

One more questions though. I do have new rubber valve cover gaskets for each side. Can I just insert the new gaskets and apply sealant on top of it and then put breather cover? Or should I apply sealant onto breather itself? What's the best way? Thanks again.

Just fyi guys, there is no actual gasket between the valve cover and the breather cover, just a small layer of sealant.
