1979 Mercedes-Benz 300SD
Starting up first thing in the morning. I've been told (mostly by people who drive gas cars) that it "knocks" but it's sounded like this ever since I've had it (for about 4 years now). Has always run/driven great, with no lack of power. Any thoughts as to whether this is abnormally loud, or is it just the way old diesel MBs sound?
