Here goes all that bragging...front engine leak
When i opened it this morning the oversparay could be found anywhere from the plastic engine cover, front piece, to the hood heat shield across the car width in line with the belt. So obvious observation that something is leaking onto the belt ( or something that is ran by the belt) hence the overspray.
Now i didnt add any liquids. Last time i added oil was a month ago, and the oil check says the level is good. No visual depletion of the coolant ( and the residue is not coolant-ish)...
i think its either the tranny fluid or power steering - is there anything else that is ran by the belt?
Never added P/S fluid in 5 years of ownership...checked it today it was on the low level, but still some fluid registering...
Is any part of trany system ran in the front of the engine?
Is there anything else i am missing that might be ran by the belt?
Going to take some pics tomorrow and post them...
Oh eah took it to a friend mechanic...he recommended to take the belt off and check each rotating component attached to the belt for loosenes and wabling....
Anything anyone dealt with before?

The fact that its ladning on the belt and gets sprayed everywhere...
I'll check the AC commpressor too...thanks for the hint
Where do i check for the front crank seal? anyone has the schematic?

How much does the P/S system has of the fluid? is it 1L, 1 Gallon?
the reason for such question, is that the P/S reservoir still has some in it..its in the lowest mark but its not like its empty...and there is a small leak puddle coming from the center of the undercarriage cover...
Now both of the hoses that lead to and from the pump are just filthy in the residue...
Anyways, the plan is to put more P/S fluid in to make sure not to seize the pump in case its the lines...and check the fluid level when i get to work...
For those who had the leak in the line, how fast did the P/S reservoir ran out? and was idling and turning the wheels enough to spark a noticeable leak?
Thanks!

I shoudl probably order a new one online...or perhaps start with the new oil filter set..and see if that works...
Soo, after brainstorming and not finding any rubber sections to improvise with the gasket...i end up throwing some hi-temp silicone at the junction area( prbably not a great idea and it probably will freeze up, but at this point i have no other good ideas)...hoping that will hold up until i get my hands on new oil filter set

When I bought my C320 about a month ago, that large o-ring on the oil filter stem was literally flat and the oil was leaking from the oil filter cap. I replaced the all o-rings on the oil filter stem that came with the new filter kit. That solved the problem.
Very likely, eesjunin's car has the same problem.
eesjunin, where are you in the Boston area? If you are in the Tewksbury, MA or Nashua, NH area let me know.

and i have been doing oil changes since day one...never had problems and always replaced the rings... I am going to buy a new filter today and replace the rings to see if that fixes the problem...if not Next step is to replace the entire plastic casette...and if that doesnt work...ill just keep on creating silicone gaskets everytime i change the oil
Clearly it can be seen the residue of cooked on oil on the outer shell of the oil filter casette...you can see theHi-temp silicone barrier that i made for temp solution...also in my case it dripped on to the belt and the belt took it all over the front of the engine and residue can be seen on the lowerside of the plastic intake pipes...more engine cleaning to be done to get it back to "eat off the engine" condition
- new o-ring (the large o-ring that seats between the timing case and the oil filter cap),
- replace the oil filter cap with the stem; I think it's around $30 or $35.
- if that doesn't solve, then the timing case may have been slightly bent... I have not seen this happen before. I would guess the timing case is around $200, labor intensive to replace.
Now, clean-up the entire area (around the belt tensioner and the timing case cover) with brake cleaner and see if there are any other leaks - I am guessing there is small leak (from the pictures you've posted earlier) from the timing case cover. There is a small gasket on the timing cover plate (NOT the entire timing case). On M112, that gasket tends to become brittle and leaks oil. See the attached picture with red circle...
If you're not busy today or tomorrow, let me know I can stop by on my way from work (Tewks to Nashua). I'll show you what work I 've done on my W203 M112.

WHat time you rive by Lowell Connector? I got to pick up the kidoes in Tyngs around 3-430 time frame. Tomorrow will not work but Wed most likely if you are working...
DO you have the black C280?

Some days I drive silver C280 and other days metallic blue C320 (THE ONE with spoiler). I have not seen any other metallic blue C car with a spoiler

The reason i asked about a 280, is beacuse i saw a black 280 4matic Komressor, the other week with purple head lights and white fogs....
