Urgent help required

[Ian B Walker]

My tame muppet and I have rebuilt a W201 engine (962). However said muppet removed all the vac lines without making a note of where they go. I have connected the obvious but find that I have a line left over and nowhere to connect it to. Does anyone have a line layout diagram that they would be prepared to share? Thanks folks (yes the one under the manifold is connected.) The offending one is red, grey, purple.

I'll have a look on my one in the morning Ian.

Cheers mate, can I phone you in the morning?

Found this ref to a 1990 w124 300e havnt a clue if its relevant or not as doesnt give colour codes for the pipes.

I not sure exactly which engine you are talking about Ian but I found details of the engine vacuum system by selecting the model menu which includes the detailed engine parts listing ( some dont unless you click on the engine heading on the far right of the menu page first) in the subsection" Inlet and exhaust manifolds"----"vacuum system" If you give me an exact engine identity i. e. w201 6 cylinder petrol 1993 I will try to get the exact page reference tomorrow.

Thanks Grober. The engine is a 4 cylinder engine from a 190E dated 1989. I have looked on my EPC and also my WIS and still cant find them. Maybe I am looking in the wrong place.

Yep, no probs. (Going to work at 1030 though)

Had a look on the one outside.
There is a rubber hose coming from the vacuum unit on the distributor. This hose goes into a white 2-into-1 plastic unit. The red, grey and purple pipe goes into the bottom of this.

Now for the other end.
Look at the manifold from the n/s wing. On the right hand of the manifold is a Y shaped rubber hose.
The other end goes in here.
The routing of the pipe runs under the manifold.
HTH, but feel free to ring me.

closest I could get but still not sure if this is the correct one. http://www.detali.ru/cat/oem_mb2.as...717.411412&CT=M&cat=504&SID=14&SGR=120&SGN=06
Merc are sneaky in that they use Y junctions to take off vacuum to numerous other devices. From gravs post- and working back from the distributer it needs a direct vacuum take off from the manifold somehow. So my guess is that the red/grey/purple pipe is a vacuum supply pipe connected to the inlet manifold at the one end in some way( directly or indirectly) and the white y junction at the other. one arm of this is the vacuum to the distributer the other you will have to check where it goes as to its function? one thing is certain the distributer has to get direct inlet manifold vacuum from somewhere

Many thanks to both yourself and Grav. Got the problem sorted thank you.

Just had a thought why I might not have had that other block Ian.
Mine is a manual
