Hello, I drive a W123 engine, 3 liters 5 cylinders in a 207D with 3.3T travel load. About 150 TKm. vehicle stood six years. Since the approx. 6000 km driven. Now I noticed yesterday at night that the exhaust manifold on the mountain, under full speed red glows. Oil consumption goes already to the limit of one litre to 1000. But even if the engine has to do a lot, otherwise less. Rowe Hd Mineral15w40. In the stand gas it blows out of the open oil filling nozzle, if I The compression is in order, between 26.5 and 29.5 bar. The pressure differences between the cylinders are all in the permissible range. Oil pressure stand gas cold 6.5 bar and warm stand gas 2 bar. Under full load warm 6.5 bar. Engine has long run out. After setting and replacing the old injection nozzles it no longer rusts anymore. What else has been done is the replacement of the control chain tensioner. The injection pump is partially overhauled before 20000 km and is new. My question would now be whether the glowing crumb is normal and if not what it might be. Thank you in advance Wieland
