I have a question whether the diesel engine can emit smoke, vapors from the oil filler port, I have a 1.6 diesel engine already turned 400,000 km, the rings were replaced at 230,000 or is the engine overhauling? At -20 degrees of frost, the engine fired twice, the injections do not pour, the injection angle is checked, the injection pump from Golf 3 1.9TD (AAZ)
