Today, I adjusted the valves of my 83 300D Turbo.
Using a 22mm on the Power Steering bolt, I turned the engine and watched for the next lobe on the camshaft to be directly opposite the rocker arm and then checked and adjusted.

It so happened that Valve 1 Intake was the first one, in this case. If u just daisy chain from any one u start at, u will have adjusted all valves with minimal cranking.

Ur comments on this method would be appreciated.
