It seems there is a small leakage on the passenger side valve cover. I moved aside the air intake duct, there is a cover approx. 3-4" wide and 8" or so long secured by 2 torx screws and 2 external torx bolts. This thing sits on top of the valve cover. I believe the hot oil fume is coming through there as oil is most abundent around this area. However, upon looking at the ML part list, I couldn't find the name of this cover. Or is this an integral part of the valve cover? I can see there is rubber in between. Anyone knows what this part number would be? Thanks.

p.s.: this is for a 98 ML with a Sept 97 production date.

Just take the cover off, get some benz black sealant in a tube or equivielent and reattach the cover. It's not a big deal, they do eventually have a small weepage on some of the 112/113 engines.

Thank you Alex. As I suspect the back stuff that got squeezed out is the broken sealant and that there is no gasket part number for that little cover.
Any chance you know how much torque to apply for those screws/bolts. I tried to use a beam type torque wrench to loosen it so as to see how much torque it was used to tighten the screws. It seems to be very low, I can't even get a reliable reading out of it. It seems to be around 15-20 Nm. Does this number make sense?

steve

torque specs.
coils-8 nm
cylinder head cover-10 nm

For those oil collectors (the part being discussed here) I'd use 20nm and reseal with Loctite 5900 (the MB approved stuff).

Thank you all. It seems I got all the info and ingradient I need to tackle this resealling project. The local MB dealer sells this stuff cheaper than fastlane's price, the parts guy was extremely helpful. Thanks again to solve my puzzle.
