A mis-adjusted valve will be prevented from closing or opening fully, resulting in the loss of compression and/or inadequate breathing of the affected cylinder. Symptoms are typically excessive smoking and difficult starting. The job of adjusting the valves is pretty straightforward if you have the right tools (like the special bent wrenches) and a good manual (like the Haynes W123 manual). If you're gonna pay someone to do it, make sure it's someone who's familiar with these diesels and has done the job before.
