Thank you. i guess i'll just fix it. In writing/thinking about the problem and then getting your descriptions and advise I'm that much more prepared.

My plan for fixing the bypassed 300D overboost switchover valve:
-vacuum test changeover valve (I tend to suspect all vacuum and pressure activated gizmos on my MB cars)
- check/test the system piping
- test the pressure switch

Missing anything?

Oh yeah, time permitting i'll do a boost pressure measurement per Marshall with a rigged up hose/gage contraption.
