What is the casting date on the block, looks like an early oil pan with minimal splash panels.
What did you do to your E9 today?

two weeks ago I had a strange encounter getting out of the garage.
I was driving 100 meters, when all of of a sudden the engine would stumble, no acceleration, RPMs would jump from idle to 1500 and then drop to 0, ...Suddenly the engine died and on starting would only run in idle. I got back to the garage, and then the car would not start any more...
I checked fuel pump, carbs, accelerator pump, power to coil and carbs.... and a ton of other things --
in the end got help from my shop:
they quickly found the culprit -the Bosch points (new - installed about 2 years ago) had a hidden break in the wire, that had started to creep in and get more and more prominent, until the points stopped working.
Out with the old, in with the new! Luckily, I had acquired some high quality original BMW NOS points a while ago.
With the NOS points in, the car runs like new - the idle is super-stable , it starts up right at the turn of the ignition, and it accelerates and the auto shifts smoothly again like new....
I would not have believed that the points and properly running ignition have such a broad reach.
I had been observing some small differences and odd behavior over the year, but with a 50+ year old car this can have multiple reasons, so I am super delighted about having my beloved E9 back in shape and running better than before!
Note to self: if you encounter mysterious behavior, consider changing your points.
Foot note: Will swap to 123 ignition going forward .
