This sounds like it might be the same thing as i definitely see all of this working. But i think my air cleaner has one more hole in it. But then i may not have the right air cleaner. Can you tell me where your air sensor goes plugged in on your assembly?My 88 and 89 300E 6 cylinders have the same air cleaner; not sure if its the same as yours. It bolts onto three mounting spots,( two on the intake manifold and one on the Fuel injection assembly. The air cleaner has a hose connecting a hole in the top of the assembly to a pipe on the cam cover. The fresh air hose consists of three parts; a piece mounted to the radiator support, a plastic flange that snaps onto the air cleaner assembly and a flexible hose connecting the two.
I think we have different set ups. My car has no air sensor other than the fuel distributor assembly, which is under the air cleaner.This sounds like it might be the same thing as i definitely see all of this working.
