Cylinder head gasket project is coming to a close. I am in need of a diagram for the vacuum hoses. Nothing exists under the hood and both repair manuals have diagrams for systems that don't match mine.

I have a 1979 528i with no egr and two lines possible on the distributor.

Sure could use some help getting everything in the correct place.

Thanks!

In the meantime you can check FAQ (timing) or related engine bay photos in Car of the month.

My '79 uses two vacuum lines, throttle body to distributor. '81 has a red rubber cap on the lower throttle body vacuum tube fitting, only one to the distributor.

This topic is regarding vacuum lines in e28, but, please, take a look.
Check the seventh picture. You have no item #1 (additional valve) in your car and line #7 is direct from the distributor to the throttle body.
