- C240 Sport 2.4L W202 engine
Hi Guys,
I have a year 2000, C240 2.4 Ltr Sport with a leaky oil cooler, leaking at the point at which it is attached to the engine. Thick coffee coloured emulsified oil in the expansion tank and the same in oil filler cap. Oil /coolant has sprayed all over the v belt. I cannot find a workshop manual anywhere for this car so I would be really pleased with some answers to my questions; Please see below.
1. Is the water pump housing shared with the engine and separated by a gasket? I guess this would explain the emulsification of the oil and water? (Dipstick oil dip seems normal colour. BUT there is mayonnaise in the filler cap that appears to have been there for a long time.
2. Is oil cooler the culprit rather than the water pump gasket? I have not attempted to remove it yet. I am not sure if this a gasket failure here causing the emulsification.
3. Lastly, what do you recommend to get rid of the emulsified oil, a little Gunk mixed in with the wash through?
I would really appreciate any help and information.
