1984 300sd Vacuum Readings

1984 300sd: Need to know vacuum spec. readings other than the'ol 20-23"
from the main vacuum hose.

Does anyone know the readings to:

transmission modulator value= 15-20"?

shutoff valve value= NEED THIS ONE

door actuator value

ignition switch

door check valve at firewall

Are the readings all suppose to be the same? 20-23 in of vacuum

I have Kent's books but do not see vacuum readings at the different branches of different systems aforementioned.

Thanks, Rafe.

85 300SD water leak left rear floor

When it rains or snow collects on the car, my 85 300SD collects a BIG amount of water in the area behind the driver's seat on the floor. The passenger side (side of the battery tray) is completely dry. The sun roof seals are dry and need replacing. Could that be where the leak is coming from? I read there are drainage holes around the sunroof and they get plugged...? The car is 80% restored after sitting outside for about 13 years. The engine is a factory replacement, but after purchasing it from a wrecked condition, there were no written records of maintainence.

87 300SDL suddenly won't upshift from 1st

Hey- I am new so please forgive any faux pas-After fueling up, suddenly would not upshift, but if moved to neutral after reaching shift point or higher rpm would slip into higher gears upon shifting back into D- your manuals on this subject seem to only cover diesels up to 1985- can you direct me to appropriate manual/technique/parts/etc I am guessing vacuum trouble but know nothing more on subject- thus I would also like a primer on the vacuum system in general-Thanks!

86 300sdl oily gunk in crossover and intake

I am putting in my new balanced injectors and injection pump stub shaft o-rings. I took off the crossover pipe to gain access to the third injector and just give me more room to put hard lines back in after cleaning them off course. I found that there is an oily gunk in the cross over pipe and the intake should I be worried about my turbo? I do have a small oil leak from the turbo (the only oil leak on the car) are the doughnuts bad turbo getting bad ect. Should I take the intake off and clean it and get a new intake gasket soon?
