Rebuilding CIS-E Distributor....
I got a junk distributor I wanted to give a shot at rebuilding and replacing all the seals inside...
Anybody know how to get the control plunger out? and does the upper and lower chambers separate?

Got the little sucker.....Hit her gently with a rubber mallet after letting it soak in carb cleaner for 2-3hours.
 Now to separate the two halfs....It seems to be stuck on really good. A small screwdriver and a hammer won't seem to separate it...Anybody know?

Seems to me when I took one apart there was just a thin gasket in there.

The 2 halves are stuck on the threaded part sticking out the bottom. Back in the day I took a few apart to confirm my diagnosis of a rusted through diaphram/metering plate. At the time there were no repair parts and all manuals I read cautioned against separating the halves. I'm not sure what you hope to accomplish by further dis-assembly. The only internal seals are around the ports in the central metering tube and if they are leaking fuel would be leaking out the bottom of the unit.

here's a rebuilder and source for parts http://www.specialtauto.com/mercedes-parts/index.html
I doubt they will be detailed but you can always ask them what they do "special" when rebuilding these...

John is a good man. Though he doesn't do the rebuilds personally. He sends cores out for rebuilds and keeps the results handy. If you have an obscure part, then he needs your core to get it rebuild. Most of the time, he has the rebuild unit in hand and will send it to you when he gets your core.
If you're lucky, he already has lots of cores for your part already and won't mind to send the part out after you've paid the core charge. If you want to get on his good side, send him a few spare cores that you collect at the PnP. Though he won't pay you for them. They'll do better that way than by becoming scrap metal. Thx -CTH

Separated two halves....put it back together.
Gonna test it out today and check fuel pressures again with the new one.    All seals are still pretty supple and everything is ridiculously clean in there....I just did a little carb cleaner action and left everything else alone.

Put it back together....Put in the car and no start.
System pressure is only 2.4bar. So looks like no go. Separation of the two halves possibly leads to non-function?

That is very interesting....funny I missed that!
That is a GREAT idea though. I just ordered a new set of injectors and I have an entire set of spare fuel lines. I will bend them all straight as they mention, hook up the new injectors and measure fuel flow so I can tell 100% that the fuel distributor is delivering equal flow.
