I have a 1987 300D Turbo with the 603.960 engine. We cut a metal plate and bolted it between the EGR valve and the intake manifold. I did not remove any other wires or attachments.

I took the car for a 500 mile run up the coast this week and did not notice any problems. It does seem to smoke less at startup.

Do I need to remove the other connections to the EGR valve? Or is it wiser to block the flow between the exhaust and the EGR valve?
