Added in the early 60ies and some documents describing the operation of pneumatically governed IP pumps show only one flap in the intake(like here):

Thanks for the information! Anybody have a part number for the gasket between the butterfly valve assembly and intake manifold? And any general maintenance you'd recommend while it's disconnected?

I'd check for excessive wear on the shaft and lubricate from time to time...

Finally got my new (well, NOS and used) parts in the mail from Germany, and starting buttoning the engine and transmission back up to reinstall. I've read the clutch alignment tool from a 90s S10 fits the 240d, so I'll try that out. Then with the new engine and transmission mounts I received, it should be a little easier putting the engine back in than it was taking it out with the seized transmission mount.

I also need to reline the rear brake shoes. I'll probably try giving this a go at home first, and then call around some truck/RV shops if I can't figure it out.

Excited to hear it run again!

Got the engine back in a a couple of hours one afternoon last week. It's been taking longer reconnecting everything! Lots of crawling underneath the van, which I haven't had to do in a while, with the engine out and everything. I' hoping to start it up again in the next week or so. Been running around the shops for different small parts -- brake fitting adapters, hose to bypass the heater, and taps and dies to clean up threads. The threads on the steering tie rod are damaged -- hoping that it's easily fixed.

I've also noticed the crank pulley has a rust hole in it. I haven't been able to source a replacement yet. Should it be the same part on the 220D/240D? No AC so only one groove.

Yours appears to only have three bolts. I have always seen six bolts, even on the early 615 in my shed. Maybe one with six holes will still work, don't know for sure.
