Knocking sound at higher revs from my 1969 200D (OM615)
I would like to consult the diesel gurus once again regarding this engine knocking sound I hear at higher revs when I release the accelerator to change gears. After releasing, revs go slightly up but doesn't seem to go down as fast as it should. I already adjusted the valves and the injection pump diaphragm was replaced recently. Could it be a fuel problem or is it something else? Thanks!
