    I have a w203 class 220cdi, at first the power just went with the car knocking then cut out, so we replaced two injectors, 3 and 4, it started but still has a horrid miss fire and knocking. We then looked and the oil was all clumpy and sluge like, so we took the rocker cover off and cleaned all the cams and put some fresh oil in with an oil flush (low ash oil) but still the same and has a and very bad misfire, any thoughts? this is killing me lol.

    Check the injectors again. If they are ok you need to do a compression test.
