Smile [Video] 1983 300D Turbo - High shaking at idle

https://youtu.be/HoaOi5KCFFw
Automatic transmission.


The turbo/air intake side of the engine shakes violently. I’ve replaced the rubber cushions under the air intake and both the intake and bracket are tightly secure. shaking stops if given a little throttle.


-Engine has all regular maintenance, except valve adjustment.
-Unknown condition of motor mounts.
-Idle is 800 stable
-Runs fine and spirited on highway. Lots of mid/high end power.
-Zero vacuum leaks. Air intake is also all sealed properly.


My first step is to buy valve wrenches and do the tuning. Then motor mounts if that doesn’t help.

If someone has a good ear, please drop some knowledge. Thanks



P.S. - @65mph My rpms sit @2750-2800rpm. Is this appropriate?
