Has anyone got any pictures or advice on how they linked the e30 brake servo to the inlet manifold? On my 320i there are are 2 pipes going into the inlet manilfod, can I just blank one of these off and put the other into the m30 inlet manifold?

Thanks

You've half answered your question there, and correctly.

I've only got this photo at the moment, but it is very simple.

I used the E30 plastic 90 degree plug thing that goes in the servo, some of any of the spare hose you've already got and cut to a suitable length and the M30 one way valve thing.

If the valve has a small stub coming off it with a tiny hole in the end then that needs to be blanked off.
Some have the little second pipe and some don't, It's for some feature of certain E32s and E34s I think.

90% of cars of all makes in a scrapyard will have a suitable one way valve, as well as M40 engined E30s and late M20s.
