BMW M30 Engine Vacuum and Intake Hose Diagram – E23, E24, E28, 535i, 635csi, 735i

March 22, 2011

One of our customers, Gary K., took the time to create the diagram presented here.  This represents the vacuum, crankcase ventilation and intake hose routing for the M30 engines in the 80s models of the 5, 6 and 7 series BMWs.  This diagram should apply directly to the following models:

*  535i 85-88
*  635csi & L6 85-87
*  735i & L7 85-87

Additionally, the earlier 3.3 liter models will be somewhat similar:

*  533i 82-84
*  633csi 82-84
*  733i 82-84

If you need replacements for any of the parts in the system, just give Bavarian Autosport a call at 800-535-2002.
