346 Views 6 Replies 3 Participants Last post by  Boathose
Hello, I've looked everywhere for the correct vacuum diagram for my Euro 1980 500se lorinser however all the ones I find are different. it has no emissions, no thermovalve, 3 connection WUR, 2 connection vacuum advance, 2 connection switchover valve, 1 connection on the throttle body, 1 connection on the intake manifold. Does anyone have a diagram like this or engine with the same set up I could have pictures of?

off the front of the engine hoses Y has one connection and the upside down U has 2
I know it's a m117 I just don't know which one. How would I find that out?
These are the closest I've found but mine has 3 vacuum connections on the WUR, mine has only 1 connection on the throttle valve, and mine has no thermovalves.
