I wonder where all this gunk is coming from???

I don't know if it's the proper thread to post my question. Jeff, feel free to move it. But I thought I had problem with the gasket cover... But as you can see from the picture I don't have any gunk in the gasket area, rather I have LOTS of gunk just below it... I wonder where all this gunk is coming from??? Any ideas? I never added any in between the intervals. The level is always steady. I check the dipstick quite often. I change it every 5-6k miles.
Any ideas if it's really harmful? Or should I use some engine cleaner or take it to the engine wash and then see what happens?
May be it's just a built up over the years?! How is your area look like, fellows?

Looks like it's coming from the cam adjuster magnet.

I thought so too... at first. Is there a seal?! Or is it built in? Should I just replace it? I looked up the part and it's $52.

There was a recall on them, I would call your local dealer and see if it's still going on. If not them replace it, there is not seal that can be replaced or fixed.

Livefreeordie I noticed that there was a clear oil right below this part... Do you think this gunk has simply accumulated dirt and this part is the culprit? Is it easy to replace? I can see just 3 torx screws...

Go to the dealer for free repair.

The problem happens on 170. On the 170 230 they will replace the leaking cam adjuster and put in the wire patch. At not cost to owner.
Have the dealer to look up the following.

170 (SLK) 2001-2004 / 203 (C) 2002-2004 Service Campaign 2009100001 DEC09 This on USA cars only.

The wire patch is a soild wire that blocks the oil from wicking in the wire loom. The wire loom is twisted wire and will wick old where a soild wire will not wick oil. You can DIY by stripping back the insulation on the wire about 3 to 5 inches and then soildering all the strands in the wire into a solid wire and then reinsulated the wire.

Good to know! I'll try to call the local dealer tomorrow if they're open. Or after the New Year =)
Hope I'll fall into this category and get it for free!

Like you and Woolly said, it's a combination of stuff accumulating over a long time. The part is very simple someplace anyone can do this job. Also like mentioned above the wire harness needs to be patched as well.

Yay!!!! I just called the dealership and they checked my VIN and this Service Campaign popped up immediately! So I scheduled my appointment and hope it won't take too long for them to fix it!
Gbarringer100 you saved my life!!!!!! Thanx a lot!!!

Yes, you might have a point in here! Didn't think about it. I was planning on replacing rubber hoses for the oil separator. Damn, all the rubber seems to fall apart...
BTW, any ideas on how to clean all this gunk? I don't know if the dealer will clean it while working on the magnetic sensor this week...
I'm not a big fan of engine wash... Should I just use a towel and a electric contact cleaner?

Update:
Took my car to the dealer last week. After I came back home all these "mechanics" did was is that they installed additional wiring harness...
Even I can read the bulletin. It says: "MERCEDES: REPLACE THE CAMSHAFT ADJUSTMENT SOLENOID(S) AND INSTALL ADAPTER HARNESS(ES)."
They didn't even bother to clean the front and see if the camshaft leaks or not...
So, disappointed and unsatisfied I took the electric contact cleaner and did my best to clean ALL the gunk I could reach! I made it like shiny new! The next day after I took my baby for a ride. After I came back home I immediately checked the camshaft sensor. So what do you think was the answer? A few drops of oil right in the camshaft sensor area! I was pissed! I wiped it clean again and the next day I saw oil drops again...
Fortunately the lady from the dealership gave me a follow up call and I told her everything and she told me that if I see any leaks I should just bring the car back. Now I'm trying to get in touch with her and make them do the proper job! If I won't be treated properly I'll post the name of the dealership and let everyone know how they treat their customers. Fair enough guys?

There must be a problem with the 171 V6 and this time they are just doing the wire patch when you come in for service.

Update:
The lady from stealership called me back with the following info:
She told me that there was an update to this campaign in 2011 after 2009 initial release which also adds the following lines:
"...PLEASE NOTE THE REPLACEMENT OF LEAKING CAMSHAFT ADJUSTMENT SOLENOID(s) IS NOT PERMITTED UNDER CONSEQUENTIAL DAMAGE, CUSTOMER REIMBURSEMENT, OR UNDER THIS SERVICE CAMPAIGN."
So, that's why they didn't replace the camshaft solenoid... It's not covered by recall anymore .
I guess the economic downturn has also affected the Mercedes stealerships and they just keep b***ing about $60 part. Too bad...

To do the camshaft sensor replacement she quoted me $
217.00+ Tax. Which I think is arm and leg for such a simple job...
Here's an excellent PDF which explains the procedure and has all the part numbers! (Note: note only for R170 )
http://www.peachparts.com/shopforum/...-m111-m271.pdf
I looked up the parts and it comes up to:
1) Solenoid camshaft adjuster (A1110510177) $54.16
2) Plug (A1119970186) $4.48
3) Sealing material (A003989982010) $15.56 (says sealing material is sufficient for 25 vehicles)

Total = $74.20 + shipping + my free labor

So, I still have money left for one of the engine mounts and a transmission mount
Ok, another project coming up =)
