1985 300sd vacuum system
 

Ok so i have been going through the vacuum diagrams in order to fix my rough shifting and I am pretty sure my 1985 300 SD vacuum system matches that of the California version cars. But i do not believe i have a California car as I am pretty sure there is no trap oxidizer. Am I misinformed on what the trap oxidizer looks like? Is it possible that the PO has removed the trap oxidizer and i do infact have a california car. or am i missing some vacuum diagrams . The reason I say my car matches the california diagrams is i have the blue vacuum transducer and the boost aneroid valve.

Use the resources button,I believe theres a picture showing the 2 different manifolds.As far as vac leaks,my S lines under black box on rocker cover had rotted,and tits.So I ran one line to green dashpot to trans valve on IP from there to transmission.The bottom of the trans valve is a vent that goes to a line you can blow thru.I disabled all other lines,EGR,Thermo valve,ect.

My car doesn't have the 3-2 valves on the valve cover. EGR and apv have been disabled already.

The '85 Cali version vacuum system is the same as the '85 Federal.

Here a diagram that will help you.

The Ca. version will have the air filter housing mounted behind the R/F headlight on both the W123 and W126.
