I have a 85 300d. It also knocks a little after starting. I let it idle until it settles down, about 20-30 seconds. I also try to keep it below 1500 rpm for the first mile or so. My thinking is that my oil is too thick. The previous owner used 30wt. I am going to change to a 15w40 Pennzoil Heavy Duty( Pennzoil has a very low pour point) this week end to see if that helps. I have only been driving the car for 3 months so I don't know what to expect. The noise may have something do with diesel engines when they are cold.
