CLK 270CDI 1.5L Oil leak under the car.
Hi all,
I recently noticed oil signs on the parking spot but because there were a few I continued with my daily routine. I parked the car at work and after 2 hours when I got back in the car I measured the oil and it showed me that I need to at 1.5 liters to reach max level.
Went back home, left the car home and I checked it a few days after. I put the car on jack stands removed the engine cover and noticed great amounts of oil under the engine...(oil pan and all the surrounding areas). Shocking, because everthing was good with the car, in 3.000 km I was suppose to change the oil , since i change it at 10.000 km, hence the oil wasn't very old, or the car neglected. I will post some photos, unfortunately the photos were made with the car not on jack stands because it didin't cross my mind to make photos when i put the car on jack stands the first time.
What do you guys think it is causing the oil leak. I will add 1.5 liters and visit a friend mechanic of mine also.

An oil leak has nothing to do with the age of the oil or even neglect. They just happen when some seal, gasket or line goes bad. I assume you have confirmed it is in fact oil and not power steering fluid or even coolant? Hard to tell in photos - it just looks wet. Assuming it is oil, it may be that that engine has some known leak spot. I don't know. It appears to be up front, so I doubt it is just valve cover gaskets. If it were me, I'd get some engine cleaner and go to a car wash and clean all that off there and get the engine all good and clean. Then drive just a short way and put it on ramps and look for the leak. Once it's all wet like that it's often too hard to find where it came from.

So...i washed the S*** out of the engine. Initially the mechanic noticed oil coming from somewhere out of the top front left side (left side when you are in the driving seat). He sayd many things such as...Cylinder Head gasket, Cylinder Head fissure, or oil cooler. I personally say it from the oil cooler. Anyway he wanted me to go to the carwash and have a complete engine wash....I did it...the engine is so clean you can lick it...Back on elevator and reved the engine and no oil leak.....again went for a very fast and aggressive drive and back on elevator....and guess what...still no oil leaks...I will come back tomorrow for another inspection. If it is the oil cooler part: 611.188.0301 can someone give me a scheme for having a more complex view on where the part is exactly fixed? Do I need to take down the inlet manifold? Because if the mechanic needs to take that down too...I better go and buy a new manifold too because mine is rather old and also has leaks.

Problems solved.
New Oil Cooler+new Oil cooler gasket fixed the problem
New inlet manifold because when they replaced the cooler they noticed also that a clap from the manifold was almost in the engine.
