Thanks for all the advise everyone, found some vac leaks, car shifts much better now. Havent decided weather to remove the trap ox or not yet. Fabracating a new tube to go into it's place looks very easy and wouldnt take long. I called MB, they told me the origional trap was replaced in 1990. Not sure if they put the same thing in or a newer replacement? I did disconnect the vac. lines to the EGR and fresh air valve (plugged lines) I cleaned the banjo fittings, then hooked a vac gage to the intake man. tapped the gage to the windshild (see pic) and pulled a good hill at WOT. The best boost I saw on the gage was 2.5 psi.
I still have to ajust the valves (tonight) and look into the adla, I isolated it and pulled vac but it wouldn't hold, leaked off prety quick.
Can anyone tell me how much boost I should see? ( 85 300sd )
Couple other questions:
I found a parts car for very cheep, thinking about getting it, it's a 89,300SE, how much trim & body parts will cross over to my 85? It has 15" wheels, will they fit my 85?
Does the kick down switch under the fuel peddle go directly to the trans? or whats the lodgic of this switch, where does it go?
Thanks again for all the help, just been into this call for a weekend now, so much to learn.
