Hello dear forum, I have been driving a GL450 for about 4 months, year 2007 with M273 V8 petrol engine 190tk. With this control chain, camshaft adjuster, oil pump, sliding rails and various small parts which belong to it with original parts have been renewed. Checking the camshafts+storage was inconspicuous. The previous owner had changed the control chain already, a cheap set for 500 something €. There were camshaft adjusters, as well as the turning gear pretty tight. e already jam-like consistency, the whole engine had deposits. Since the engine was running quite impeccable during the purchase and afterwards and the rest was also in good condition I had hoped to have made a good purchase at that time. Because of this bad condition I thought I would do something good for the engine with original spare parts. My workshop cleaned the scmodder, rinsed the oil wells, even 2x. On the test drive the car ran like a sack of nuts. The engine spits out massive oil from 2500 rpm on the test drive. Hot on 2km 1-2L oil. Towing, Kat clean up with Mercedes contact, because this did not happen to the workshop. Afterwards a centrifuge was renewed, as well as the oil separator, which did not bring any improvement, still came massive oil out of the exhaust. Without KGE, i.e. hose pulled off the car ran great, as it should be and there was no oil. But this is the way one is allowed today The problems did not exist before. There was an M8 threaded pen in the middle of it and clogged it up. Why is the oil coming through there so strongly from 2500U? If I see the small holes on the oil separator, then they are not there to eliminate a flood, but only drops. If the piston rings were over, would there have to be oil there even if the KGE had been pulled off, or would the car have to be there before the repair Where does the oil drip out of the separator? Does anyone know such a problem or has their theory about it?
