Bought a 83CD last week, have been looking for a turbo. Picked up the 83 with new MB installed motor 20K miles ago. Motor runs great, but tranni has vary hard shifts. Replaced tranni filter/fluid, made shifts a little more consistent. Also did diesel purge on IP. Today started tracing vacuum/lines. Found that I do not have any vacuum going to tranni. Traced lines to the 2, 3/2 valves on top of valve cover, and found that two of the lines were broke off. Questions:

1: Have done much research, and it looks like many just delete this whole setup, should I delete it, and if so where can I find a good write up??

2: Should I just order the new 3/2 valves and get it running/shifting correctly before doing EGR delete?

3: The 3/2 valve set up on the valve cover, uses 4 vacuum ports, but I only have 3 vacuum lines going to it. Am I missing a vacuum line some where??
